Prosecutors wrapped up closing statements of the morgan hill man accused of killing High School Student sarah lamarr, as she walked to a bus stop on her way to school. Jesse gary has been covering the trial since it started. How did prosecutors and their statement to the jury . Reporter prosecutor david boyd asked the panel of 12 to find torres guilty of kidnapping sierra lamarr and in his words, im quoting here, do unspeakable things to her and kill her and dispose of the body. Boyd played a police video of Garcia Torres getting interviewed by detectives. The primary suspect admitted he did not fully understand the concept of dna and he did not understand how it got on her clothing. Boy told jurors somehow, someway his dna made it onto sierras pants adding he knows what he did, wanted to do it and was compelled to do it. There would have to be, im quoting again, conspiracy of improbabilities for jurors to find the defendant not guilty. He caused by saying dont reward his cunning he handed closing statements yielding the floor to the defense attorney al lopez they hammered at the case based on circumstantial evidence. Lopez used a shame bucket placing balls in a bucket each time he shut down a prosecution there is in there was no evidence Garcia Torres tried to carjack and kidnap three separate victims from a safe way shortly before lamarr went missing then lopez attacked the crooks of the case, no evidence she is dead, perhaps she runway. Prosecutors cant prove how his dna ended up in the suspects read jetta and some samples are tainted. Lopez reminded jurors that she wasnt happy, wanted to run away from home and packed a suitcase to that end. Torres admits he was driving in the area of the bus stop the morning the 15 yearold student witnessing in 2012, but he was there 10 minutes before she left for school and no one saw his car and there is. It is not the defenses job to prove the case is the prosecutions job with the defense is saying just is not enough evidence here to suggest sierra lamarr is dead and two Garcia Torres is responsible for her murder. The defense had a top ten list of reasons why he is not the killer including sierra lamarrs body has not been found. There were no murder weapons, no tools, no witnesses and no crime scene and sierra lamarr is missing but that does not prove he murdered her. Defense lawyers wrapping closing statements right now, hammering away from the lack of intent, reasonable doubt and possibility of the killer was driving brown car seen driving erratically in the area. Police never focused on that, they focused on Garcia Torres and that raises reasonable doubt. After he is done the prosecution gets a rebuttal that will probably come tomorrow. Jurors could get the case as early as friday. Im curious this bucket of shame tactics seems unusual having that played for the jury . It was very interesting i talked to Stephen Clark about this, we are of the same mind where you know what it is a nice touch because it makes the connection with the jurors. The prosecutor, boyd, has a very different style. Very businesslike, by the book. No connection with jurors met as part of a trial you have to make a connection with jurors. I think that was lopezs way of making a connection with juries and making a point this is all circumstantial. No direct link that says my defendant is guilty and plenty of reasonable doubt from the biggest pieces today, the timeline Garcia Torres in the area but 10 minutes before sierra lamarr left for school and no one saw his car in that area, the second thing the brown car driving erratically as if someone was struggling, police never pursued the lead. Those two things may be enough to raise reasonable doubt. Lopez kept going back to that. If there is a scintilla of reasonable doubt you have to quit. The jury has a lot to consider. I am joined by legal analyst stephanie willis. You heard in jesses report some of what the defense tried to do laying out its theory about what happened to sierra. I want to start with this shame evidence and visuals. How do you think that will go over with the jury . Using visuals is a very important way to connect to jurors. It allows them to see what the defense is trying to say during closing arguments. A way to tie and perhaps Something Else to look at, something for members to coincide with what the defense is trying to say during closing arguments. We have to remember it is simply an argument, not necessarily evidence. The jury will have to weigh what they found, what was presented as evidence and use it during deliberations. Something else they brought up again, the defense, is no body has ever been found. Right. Is a very, very key point. There was no crime evidence, no body found that leads to the point that sierra may still be missing. Highly unlikely in this case, that is what the prosecution is trying to prove beyond a reasonable doubt. Through circumstantial evidence some being dna the fact that he is trying to kidnap individuals in the past that he in fact did commit the murder in this case. Something theyve done through the trial really challenging dna evidence implying it may have been contaminated. What you think jurors might make that argument . Dna evidence has been extremely apartment way. We live in the data age for jurors like to see dna evidence specially was shows we have like csi. Having dna evidence is key to jurors but during instructions and Opening Statements the prosecutor will let them know whether or not dna evidence will be admitted. In this case they said they did find dna evidence on her pants. The defense is saying that it wasnt necessarily mr. Torress dna and that the scene was in essence contaminated by investigators which will lead to reasonable doubt that the jury considers that evidence. My final question a lot at stake here this is a Death Penalty case and the fact that the defense use this top ten list, latenight style, the fact they did that and used visuals, to think the jury might feel like it is too gimmicky . I dont think so in my opinion, only because there is a lot on the line, dealing with someones life. Mr. Torres has his life on the line. You want, as defense attorney, you want to advocate and zealously represent your client. Do everything you possibly can to demonstrate to jurors that this is not what happened and that the prosecution did not prove beyond reasonable doubt. Always a pleasure to talk with you. We will be waiting for this case to go to the jury and see whos argument they believe the defense or prosecution. After a string of criticism Facebook Says it is adding thousands of jobs.
