Current. Reporter Matthew Mayhood explained its part of his organizations evolution into a regional agency. We are not just san joses chamber of commerce, but we are Silicon Valleys chamber of commerce. Reporter san jose was found to be in the top 10 most forgettable cities in a survey. This Business Owner said he had to change names because its completely separate from the old san jose symphony which went bankrupt, but having Silicon Valley in the name hasnt been the financial boost people thought it would and the symphony might even change its name back to san jose. I think long time we would like to be affiliated with the city of san jose more than the title Silicon Valley. Reporter might it someday lead a reverse trend if and when the current Silicon Valley craze ever sputters out . Cities have already endured for centuries and centuries. San jose might yet outlast Silicon Valley as a brand. Reporter in san jose, len ramirez,s about be with. Breaking news, chopper len ramirez, kpix5. Breaking news, chopper 5 just wrapped up from a rescue at mile rock beach at lands end. Earlier we watched crews as they set up their rescue plan, the man sitting frozen partway down the cliff waiting for help. One rescuer pharrelled down, put rappeled down, put a harness on the man and took him back up to safety. Earlier today a man out walking with his dog fell off a steep cliff at daly citys thornton state beach. Kpix5s Juliette Goodrich explains the man was trying to reach his dog right before slipping to his death. Edient fo reporter the heartbreaking recovery unfolds after a 67 yearold man falls down a 500 foot cliff at thornton state beach. He was trying to rescue his dog. The Golden Gate National park ranger said the mans dog got away from him and when he tried to go after it, he fell to his death. You can see the dog pacing and barking on a perch as if to sense something was wrong. This is a popular area for dog walkers. Yeah, no. That dog definitely knows like if youre hurt, no doubt. If the dog knows that the cliff is there, sometimes dogs get overstimulated and they run when they dont know all the facts, you know. Reporter ted leblanc and his friends out hiking today say the terrain is very steep. Sometimes things can like move around. So you just got to be careful and, you know, definitely always be on alert because like rocks can tumble. Reporter rescuers air lifted the mans body from the bottom of the cliff. Later they helped the dog get back up the steep cliff to be given to the victims family. Park rangers say they dont have a leash law, but they do advise you to walk your dog with a leash or at least know they respond to voice controls. You can see just how steep the path is and how the cliff comes down very sharply. They say please be careful if you do come out here. Its extremely windy today. In daly city, Juliette Goodrich, kpix5. The feds are taking action against a special ingredient found in marijuana, one that is used for medical purposes. This battle is playing out in a San Francisco courtroom. Tonight kpix5 reporter kiet do introduces us to a south bay family who has a lot at stake. Reporter five years ago in Santa Clara County a baby was born, his name . Zachary. He was normal for all intents and purposes. He is a special little boy. Reporter but a few months into life zach began to twitch. His arms and legs would flail. This video was taken at the Doctors Office where the baby was actually having seizures, four in under a minute, hundreds in the course of a day. His father remembers with tears in his eyes. The longest couple minutes of my life was walking from the Doctors Office all across the hospital to their intensive care unit for babies in my arms, hes just seizing. He had essentially no normal brain activity. It was just background seizures all the time. Reporter zach was diagnosed with a dangerous form of epilepsy. For a year we tried basically every medication we too. Could, last i totaled it like 12, 14. Reporter the drugs did not stop the seizures. They also had devastating side effects. He was just empty. His eyes were glossed over. He wouldnt look at you. Reporter doctors told them zach would get worse, that zach would be better off institutionized. It was very hard to swallow. Dan and i were horrified. Reporter then late at night unable to sleep. Stumbled upon a show showing a child having a seizure and somebody gave them a liquid and their seizure was stopping. Im like what the hell is going on here . Reporter whats going on is that the liquid contains a special cannabis compound called cbd. Its found in Industrial Hemp and in marijuana, but give cbd to a baby . Zachs mom needed convincing. I was really against it. I was always told drugs are bad. Reporter unlike the tch found in marijuana, cbd did not get you high. The boys neurologist said the couple had nothing to lose. So with cbd zachs brain waves. Reporter ed to normal. Within like waves returned to normal. Within three weeks to a month his brain waves returned to normal. Cbd for us was a miracle that changed his world. Reporter now cbd is at a legal crossroads . The intersection the 9th circuit u. S. Court of appeals in San Francisco in front of a threejudge panel. Whats the industry afraid of . Weve seen this drug code utilized week after week since its enactment to seize, to cause criminal enforcement against lawful operators who require no dea registration. Reporter the hemp industry filed a lawsuit against the dea challenging a new drug code. That new code says that all cannabis extracts including cbd are controlled substances and illicit. Its unfair to the public. Reporter above rovan represents the hemp industry concerned the dea is outlawing all cbd, but unlike hemp its not a controlled substance. This gives all of the agencies and Law Enforcement across the country the right to stay look, this rule made those extracts controlled substances. Reporter the crackdown has already begun. A week ago authorities raided and padlocked 23 stores near nashville, tennessee, because they sold products containing cbd, an ingredient the sheriff called illegal. Its my understanding that that was from Industrial Hemp, not from marijuana. Reporter as for zachs parents, the cbd they use comes from marijuana. They give it to zach three times a day and that little boy has defied all odds. Hes walking. Hes talking. He definitely has some developmental issues, but we dont have seizures really anymore. Reporter the family went camping at yosemite and recently visited the car museum in San Francisco where zach had a ball. Hes an angel. Reporter the concern . If the law is now attacking cbd derived from hemp, is zachs medicine next . In san jose, kiet do, kpix5. The dea says it needs the new code to better track cannabis extracts for Research Purposes as well as better live up to International Treaty obligations. A decision is expected in a few months. The other big story that we are following this evening, the cold weather. Some fresh snow fell in the sierra today and even some parts of the bay area. Lets take a look outside now. This is live. Its going to be another chilly night. Temperatures will dip into the mid20s. Take a look at some video just into us, a mix of rain and hail late this afternoon in oakland. This is in the rockridge area. People were taking out their umbrellas and bundling up to stay warm and dry. Then in the Santa Cruz Mountains a dusting of snow covering roads at the crest ranch Christmas Tree farm just west of boulder creek, the roofs of some homes there covered with snow. On Mount Hamilton frost covered this camera at the Lick Observatory. Cold weather can be harsh on your pets. With more on that lets go live to kpix5s katie nielsen. Katie . Reporter were here in downtown napa. Weve seen a lot of people walking by bundled up a lot warmer than they normally would be this time of year. Thats because the low tonight could be around 27 degrees and believe it or not, the most vulnerable animals are actually the chickens. Chickens look at. Im trying to get them. Look. Reporter 2 1 2yearold hudson considers himself a professional chicken wrangler. He only has three chickens, but they have a cool in the backyard for bo, choo choo and chickee. We have a little heat lamp over there. They stay pretty warm at night. Reporter while hudson would rather bring the chickens into the house for the night, his dad andy has other ideas. Weve looked all over for chicken sweaters, but we cant find them anywhere. Reporter yup, you heard him right, chicken sweaters. Supposedly its a thing. Any chicken sweaters . Not today, not today, but maybe soon. Reporter wilson feed has seen plenty of customers getting their coops ready for the record low temperatures. We sell a lot of shavings, bedding and straw. Reporter the vineyards are preparing, too one hard freeze on budding chardonnay vines could mean huge losses. Once it gets so cold were really at the whims of mother nature. Reporter the low hit around 30 degrees last night, but the air kept moving mean nothing frost and no freezing vines. Tonight could be a different story, so at this business theyll turn on the fans around 1 a. M. Keeping the air moving, it keeps that cold air and potentially ice from forming on this little bud. Reporter with those record low temperatures tonight just remember cover up the plants. Bring the pets inside. And dont forget the sweaters for your chickens. In napa, katie nielsen, kpix5. That just happened to be at the top of my list. Weve got the coldest night on tap for the bay area in 2018. Its no wonder they are bundling up, santa rosa 27, san jose 30, walnut week 27, the big chill is in the bay area. Weve got the forecast coming up. Also straight ahead the San Francisco mayoral candidate getting behind tasers for city police. A bay area city called out for wasting too much water, but city leaders say wait. The mistake they claim put the town on the list. And also still ahead 3d printing isnt as complicated as you might think. The new way you can make your ideas a reality. There are two types of people in the world. Those who fear the future. And those who embrace it. The future is for the unafraid. Supervisor london breed who is also running for mayor to answer que for weeks weve been trying to get San Francisco supervisor london breed who is also running for mayor to answer questions about this. Rpac that supports london he means this guy cut a back room deal with these guys that helped this Guys Campaign for mayor. This political ad was created by a superpac that supports london breed. It accuses two supervisors of conspiring to remove her as acting mayor to help her rival, mark leno, win the special election in june. Leno has called the ad shameful and a smear campaign. Did london breed approve of the ad and does she know who paid for it . Back on february 5th our phil matier asked her those questions. Did you get a chance to she obviously walked away from phil. The next day kpix5 reporter jackie ward also asked her about it. N reporter did you get a chance to watch that ad . Yeah. Unfortunately im not going to be able to answer any questions about anything other than this press conference. Vity of anything as it relates think the vo well, today phil matier asked her about the ad yet again. Phil, im not going to talk about that commercial and the negativity of anything as it relates to this race. What i think the voters care about most is what am i going to do to address the housing crisis . What am i going to do to deal with homelessness . What am i going to do to deal with Public Safety . We have to focus on the issues and less on the political stuff that people are sick and tired of. So we have asked london breed about the ad three times now. It looks like shell never answer. London breed did want to talk about tasers for police. In fact, she told phil that she supports giving tasers to San Francisco police officers. Oh, my god, drop it reporter since the 2015 Police Shooting of mario woods few issues have jolted San Francisco politics as much as the question of police use of tasers. Studies have shown when departments get tasers, that officers use tasers more freely. Reporter and now tasers are taking the stage in the San Francisco mayoral race with board of supervisors president and mayoral candidate london breed saying shes now in favor of the shock guns. Her reason . I hate guns. Guns have destroyed the lives of so many in my community. Reporter supporting tasers, however, immediately put breed at odds with her progressive rivals in the june race like former state senator mark leno. Tasers, yes or no and why . No until we implement all of the reforms that the department of justice put before the San Francisco police department. Reporter candidate and supervisor jane kim also said no to tasers for now saying that instead, we need to deescalate situations safely. This keeps everyone safer. On the other hand, theres former supervisor Angela Alioto who has long supported giving cops tasers. Theres a total lack of common sense in this city when it comes to certain things. Reporter at the same time alioto noted breed did not publicly come out for tasers until she was running for mayor. Oh, she came out for it . Shes been against it for years. Wonders never cease. Reporter you havent always been an advocate for tasers. I have been an advocate for police reform. Reporter recent polls show seven of 10 voters back police using tasers in San Francisco, especially on the citys more moderate west side. The loudest sound at city hall seems to be the progressive activists, but at the end of the day its those absentee voters, those homeowners, those ethnic communities that vote. I think its a distraction, also, because the thing im hearing from everybody right now is about car breakins. Reporter whether or not tasers are on the top of voters minds, however, is not the issue. Tasers and other issues like this are sort of signals about where people stand on Public Safety and in relation to the police and thats also something her voters are looking at as they contemplate their choices. In San Francisco, phil matier, kpix5. Returning to the topic of weather, you can see whats happening. On the kpix5 hidef doppler its picking up the potential at least of snow falling on the road at Mount Hamilton, the road with 365 curves in it on highway 130, one for every day of the year, and north around the san jose foothills it looks like there could also be a few snowflakes out there. By the time we get to weekend we will warm it up slightly. For tonight it will be clear and cold. Inland will be down to the mid 20s and no surprise. Those freeze warnings are up through tomorrow morning at 9 a. M. With plant damage possible. Be sure to bundle up. Low forecast for tonight shows everybody under 40 degrees, coldest night of the season with pacifica 36, morgan hill 28. Clearing skies dont help either. The heat such as we had during the day just gets right back out into space without an insulating cloud cover. The result . Tonight petaluma is down to 27, novato 31, mill valley 33 degrees and in sausalito 34 and chillier at ukiah and lake port and clearlake. In the extended forecast after a chilly night tonight a few high clouds tomorrow, a snow shower or two in the upper elevation of the bay area. Sometimes you forget we live in a mountainous region, but when you see whats happening this hour, you are reminded weve got mountains above 2,000 feet in the bay. Extended forecast calls for numbers to recover by 60 degrees by the weekend. In the meantime it could be cold. Well bundle up, thanks. Still ahead the lucky Central Valley innout employee who snapped a selfie with a special guest at the drivethru. Nba allstar game fallout, any National Anthem singers out there looking for a gig . Its play ball in arizona, a live report from vern glenn coming up from scottsdale. Working of the spring. And vern glenn was there, he joins us live from scottsdale. Vern . The giants took the field in arizona today for the first full squad workout of the spring and vern glenn was there. He joins us live from scottsdale. Vern . All right there, dennis. It was nice seeing these fellows out this morning. I saw high fives. I saw bro hugs. I saw laughing with some of the faces we are familiar with and the new guys got acquainted, but its not just changes on the roster. Its changes on the coaching staff, too. In fact, hunter pence might think about getting one of those hello, my name is stickers. Im really having a lot of fun working with alanzo and rick shoe and let me make that clear. Is that his first name . Sounded right. I always call him shoe. Pence was part of the featured group during batting practice along with buster posey and the offseasons big addition, Evan Longoria and andrew mccutchen. Im eager to be here and i think everyone kind of feels that excited and fresh feeling. Reporter another one of the new faces in camp is veteran outfielder Austin Jackson who hopes to win a world series ring after the giants denied him in 2012 when he was with the tigers. I actually was messing with some of the guys today. I said i blame all of you all, every single one of you all. I blame you all because its you alls fault i dont have a ring. Reporter jackson is quickly warming up to being in the orange and black. It might grow on guys after a while. You never know, you know. Change is good. Reporter you go three for four a day in these spring
