A person who was close to the shooter responsible for the worst mass shooting in American history has the same question as nearly everyone else: Why did he do it?
Seddique Mateen said he didn’t know of 29-year-old son Omar Mateen’s plans to shoot up the Pulse nightclub in Orlando, Florida, on Sunday morning, which killed 49 people. Had he known, the father, who is from Afghanistan, said he would have intervened.
