police van and not during his videotaped arrest. it's these images that thrust baltimore into chaos, 25-year-old freddie gray being hauled into a police van. but determining what the video doesn't show may prove just as explosive. today, the 30-man police task force in charge of investigating gray's death turned over its findings to prosecutors ahead of schedule. >> i understand the frustration. i understand the sense of urgency and so has the organization, and that is why we have finished it a day ahead of time. >> reporter: "the washington post" reports a sealed baltimore police document quotes a prisoner who briefly shared the van with gray. the prisoner is dante allen. this surveillance video shows the police van stopping to pick allen up. freddie gray was already inside. the two men were separated bay solid metal partition. they couldn't see one another. today allen spoke to wbal's jane miller. >> we went straight to the police station.

that's all i think about. >> reporter: brooks doesn't want his son to be another statistic. >> i don't want the streets to have my son. i will fight to not let the streets have him. >> reporter: how much do you appreciate that he stands here with you? >> a lot. most kids don't have fathers that would do this. most kids don't even know their fathers. >> reporter: if you had to do it all over again, what would you do? >> i would have stayed in the house. >> reporter: for carlos jr., who returns to court in a month on misdemeanor charges, an encounter with the criminal justice system that both he and his father hope never to repeat. rehema ellis, nbc news, baltimore. we turn overseas now as the death toll in nepal climbs towards 6,000. there's still more new video from the moment that devastating earthquake struck. shot by a tourist in a square outside kathmandu, people frozen in place crouching to the ground as ancient buildings began to crumble around them. meantime, the increasingly grim search for victims took a welcome and emotional turn today

loeb and vergara are now split, but he wants control of the embryos writing in "the new york times," "in my view, keeping them frozen forever is tantamount to killing them." loeb wants a surrogate to be implanted with the embryos so he can raise the babies on his own. but in a statement to e! vergara's attorney says she is content to leave the embryos frozen indefinitely as she has no desire to have children with her ex. an agreement both partners signed states any change to the embryos must be mutually agreed to. in court documents loeb argues the agreement doesn't state what would happen in the event of their separation. ultimately the agreement may not matter. >> unless there is a compelling reason to force somebody, you know, to potentially become a parent, the court has decided with sofia's side. >> reporter: loeb asks "when we create embryos for the purpose of life, should we not define them as life rather than as property?" >> it sounds like he's trying to bring this

very fiery philosophical religious debate into the courtroom. >> he's really trying to hang his argument on the idea that these are little people, and whatever else happens, they ought to become bigger people, that is to say, babies, but courts have never recognized, never, embryos as people. >> reporter: but the law surrounding frozen embryos is still a work in progress. cases like this one continue to shape it. stephanie gosk, nbc news, new york. >> we're back in a moment with the fight of the century, and you won't believe how much people are paying to see it.
