you can see abu laban enter the garage to the apartment building. he runs toward the apartment where anna, maria and ray were sitting on the couch. then around 10s later, you can hear gunshots. ali leaves the apartment and he seems to be in a panic trying to figure out his next move. 45 seconds later, abu laban leaves the elevator and is seen pacing back and forth between the elevator and the apartment before he finally decides to go back inside the apartment where he just shot his wife and her friend. screaming out anna's name, prosecutors say he was trying to cover his tracks, pretending that he found them, but he didn't count on a neighbor's security camera recording a call to his mom. >> i just like to hear us. i just like him. >> prosecutors say it was all part of an elaborate plan. the motive? his wife asked for a divorce. he installed a listening app on his daughter's ipad and waited until he heard them together and put his plan into action. >> right after you shot anna in the head, you pushed her head down into ray's lap, right? >> oh, god.
