walk us through how the tragedy happen. >> yeah. so what happened in the early morning hours wednesday, the manslaughter police department was basically -- the minneapolis police department was investigating out of nearby st. paul. as you mentioned, the attorneys for lock say he was not the target of the investigation and police say he was not named in any of the search warrants. as police burst through, it basically seems to wake up lock who is wrapped in blankets at the time. as he tries to get up, he is seen with a gun. officers shoot. now, police say the gun was pointed in the direction of the shooting officer. but based on the videos we've gotten and the picture, we can't independently confirm that. the parents are speaking out for the first time. they had to watch that video before it was actually released. take a listen to his mom. >> never would i have imagined that i would be standing up here
