menoned, lots of questions about his motive. we talked to his friend today that tell us they cannot believe the darion aguilar is the face behind the deadly shootings. >> the house that you see behind me is where the shooter lived and has been very quiet all day long. residents who live in this neighborhood say they knew very little about him and that is how his friends are feeling this evening. they say they feel like they don't know him and are trying to figure out how such a passive young man could have attacked people in such a violent manner. friends describe him as a calm person who is into art and music. he kept a low profile at blake high school where he graduated last spring. boy met him their freshman year and he says the 19-year-old was down to earth. >> he loved science. how could someone take care of his plan to do this? he is not violent. >> he and his mother rented this home in college park. he had recently taken a job at a dunkin' donuts. he interacted very little what others. >> it almost sounds like he was real
