haley britzky: when he opened it, she saw vanessa guillen inside of it.of the body. they tried to burn her body, but it wasn't burning completely, and that's when they buried her remains into three separate graves in the area. andrea canning (voiceover): as for the murder itself, investigators say it happened on april 22 in the arms room where robinson worked, where there were no security cameras. andrea canning: did cecily say how he had killed her? she told authorities that robinson told her he'd hit her several times in the head with a hammer. it must just tear you apart when you think about her in that room. yes, taking a human's life that way. it's disgusting. i hate to think of it because i can just feel, more or less, the panic that she was in. andrea canning (voiceover): vanessa's sisters find comfort in the heartfelt murals honoring vanessa and can only imagine why she was killed. i felt that he sexually assaulted her in that arms room. andrea canning (voiceover): they believe he then silenced vanessa by killing her. no one was there to help her.

officials are telling me and my colleagues, natasha bertrand and haley britzky that a military flightcarrying migrants will be. >> heading to. >> guantanamo bay today. of course. >> remember president. >> donald trump last week announced and directed the government to set up or rather, to expand a base on guantanamo to hold migrants. there's already a migrant operation center that exists there. well, they are outlining plans to expand that to 30,000 people. i have spoken with sources who say they are currently setting up multiple tents to hold migrants there. one of the questions that attorneys within the department of homeland security and the pentagon were working on over recent days was whether or not they really could take the step of taking someone from u.s. soil and taking them to guantanamo bay. well, it seems that they may have resolved that because there is a flight that we know is going to be headed there today. but this is part of a massive undertaking by this administration and an unprecedented one at that to set up such a massive facility not only for migrants interdicted

. >> yes, there are legal experts told my colleague haley britzky that this all stems from that executive order issued by president trump this week. that seems to give him huge power to interpret the law, which these experts fear could cause military commanders to be dissuaded from refusing unlawful orders. now that executive order says that trump, quote, shall provide authoritative interpretations of law for the executive branch, of which the defense department, of course, is a part. now retired air force colonel who previously served as the air force's chief prosecutor, told cnn that he worries about this chilling effect that this could have on military judges and the military justice system, saying, quote, i can definitely see people hesitant to fulfill their duties because they're afraid trump will have them punished. now, a concern that we heard was that military commanders who typically might consult their military lawyers on an order if there are any legal questions, could simply stop doing that and just follow a trump directive. given the sweeping new executive order. and we shoul

so my colleague haley britzky, she has some great reporting on this. and essentially the order that trump signed earlier this week, it says that the president, quote, shall provide authoritative interpretations of law for the executive branch, which dod, of course, is a part of. and it's raising concerns among legal experts who say that that could have a chilling effect on the decision making amongst military judges and the military justice system. essentially, the concern is that military judges, for example, won't be as inclined to disagree with an order from the president, who is the commander in chief and who does have the ability, of course, to interfere with the military justice system. but they will be less likely to push back on a kind of unlawful order. and military commanders in particular, they could be susceptible to this. according to the legal experts that we spoke to, because whereas sometimes they will or often they will go to military lawyers and say, is this legal for us to do? the concern is that if trump's executive order and his le
