Is ongoing and more people could be charged. The Montgomery County police and all of our partners will work to hold every individual responsible who was involved with the abduction and murder of the lyons sisters as well as the ongoing conspiracy to conceal these crimes. Reporter prosecutors said they are also investigating the possibility that lloyd welch may have been involved in other child abductions across the country. So they are retracing all of his steps, starting 40 years ago. Track welchs activities from the time that this abduction occurred through to when he was incarcerated. Its we are our investigators, thats part of what they have been doing all over the country. Reporter Court Records released today show investigators recovered bone fragments and remnants of a burned plastic bag on a hill side property in a remote section of Central Virginia where the welch family once had property. As john and mary lyon, the parents of the two girls sat nearby and list and to prosecutors announce the murder charges the Montgomery County states attorney explained why the case is being prosecuted in virginia and not here in maryland. We think this is the best thing for the case and people who are interested in bringing justice to the lyons family we have talked to john and mary they next actually why we are doing it. Reporter now, lloyd. We will be extradited from that delaware prison to virginia within the next 30 days. Shortly after that he will have his First Court Appearance, the trial could begin within six months, it could take up to a year before that trial wraps up. If he is convicted, he could face up to the Death Penalty in virginia. Vance, back to you. For family members of the victims and others living in Montgomery County, the]5 announcement today was welcomed. Tisha thompson continues our coverage now with a look at the decades long investigation. Tisha . Reporter jim it is rare for a cold case to have as much of an impact as the lyons sister case had here in the d. C. Area. It frightened so many people and it changed the way kids grew up in this town. It was spring break when 12yearold shelia and her 10yearold sister katherine, walked to Wheaton Plaza. They hung out at the mall. They ate pizza and then they vanished, setting off a massive search that would last for decades. You ask anybody that lived in Montgomery County, they can tell you a personal story about how they or their family was impacted. Reporter Montgomery County police chief tom manger was a College Student went sisters disappeared. This was something that had an enormous impact on this community and the feeling of safety for your children in this community. Reporter chief manger says the break came when the cold case detective matched a mugshot of Lloyd Lee Welch from 1977 with a sketch based on a description given by one of the girls friends who had been with them at the time mall. Police interviewed welch seven days after the sisters disappeared. The 18yearold drifter and carnival worker said he had seen the girls get into a car with a man and leave, but police at the time thought he was being untruthful, according to Court Affidavits. He would later be convicted in the 90s for sexually assaulting young girls in delaware and south carolina. Noncooperation has prolonged this investigation and made it difficult. Reporter investigators previously said welchs uncle, richard, worked as a Security Guard in the wheaton area when the sisters vanished. Last year, news4 reported women who were teenagers in the 70s had told police about a male Security Guard who tried grab them in or near the mall accusing them of shop lifting. Then this february, unsealed Court Affidavits described how lloyd welch now admits he left the mall with the lyons sisters in a vehicle, but it was his uncle who sexually assaulted one of the girls. The uncle has been named a person of interest, but so far, has not been charged with a crime. Leave with you the words the investigation continues. We have indicted one individual and the investigation continues. I think theres a logical conclusion you can reach. In todays news conference, prosecutors made it very clear that this is going to be a very difficult case to try. Its been more than 40 years. The young girl, for instance, with him that day, she would now be in her 50s that just puts it makes you realize that they are dealing with witness testimony from someone who was a little girl who is now going to be in her 50s. I know you have been covering this case for a long time, and you were a little girl. I was one of the blonde little girls that got told you cant walk home by yourself. I mean it really it changed everything and i dont think if you just moved to this area, its hard to get that across that this was the case that changed everything for folks in the 70s and 80s. What about the statute, the murder statute . How does that play into i mean its been 40 years. 40 years, today learned something very interesting, which is that investigators have to use the statute from 1975. And i wrote it down here its firstdegree felony murder we are intent to defile, which means according to the prosecutor, that someone had to sexually abuse, exploit or mollest the victim during an abduction that resulted in murder. And so, they are going to try the case on the 75 statute and not todays modern day murder statutes. Talk about the fact that investigators found bone fragments in the area where they once lived, the suspects once lived. Anything other than that, that we know about . Thats the interesting thing. So, that bone fragment is coming from an affidavit, a search warrant that was unsealed today. And there is language about bone framgt s fragments, but a lot of language where they have a nobody care dont have an autopsy where somebody was murdered. No body case, you assume they dont have any remains as of yet they can definitively link. They said that is a real challenge because you are going to have to prove. A the lyons sisters are dead, as awful as that is then you have to prove how they died and without a body, thats very difficult thing. Intend to defile part, the statute, all tough to prove as well. I have been told . One of the worst cases that investigators have ever had to look at. So we will find out more. More to come. Coverage of todays murder indictment continues. In our next half hour Chris Lawrence will be looking through the warrants and have more on the evidence and the fear that gripped a neighborhood in maryland for 40 years.

The president says the inspections that will be under way in Uranium Mines in that country will be enough. If, in fact we are counting the amount of uranium thats being mined and missing on the back end, they got some explaining to do Vice President biden will be lobbying democrats on capitol hill who are still sceptical about the deal. Many republicans say them fight it as hard as they can. Perhaps the most vocal opposition has come from israeli Prime Minister benjamin netanyahu.

Reporter the jury made up of nine women and threehether the gunman james holmes was sane at the time he committed the crime three years ago. They have been instructed to consider whether holm was incapable of knowing right from wrong or if he had a mental disease or defect. They got the case last night after closing arguments. The prosecutor emphasized the preparation and precautions that holmes undertook in an attempt to show that he was, in fact not just mentally ill but a deceitful and evil person. That sounds like Death Penalty talk to me and the defense emphasis time and time again that he did not ask for this Mental Illness and but for the Mental Illness this shooting would not have occurred. Reporter defense argues holmes had delusions he could increase his selfworth by gaining Human Capital and killing people and he should be sent to a state mental institution. The prosecution claims holmes was legally sane and should be sentenced to death. Theres no time limit on the jurys decision. If theres a guilty verdict the Death Penalty phase would follow.
