Mother of man missing after Orlando shooting says her son is dead

UPDATE: Christine Leinonen, who shared her grief with reporters Sunday as she awaited word of her son, told ABC News she was told her son was dead.

Earlier story:

Many are still awaiting word on whether their loved ones are among the 50 killed and 53 hospitalized in a mass shooting at a gay nightclub in Orlando.

Thirty-two-year-old Christopher Leinonen was at the popular Pulse club and is missing. That’s according to his mother, Christine Leinonen. She drove to Orlando at 4 a.m. She hasn’t heard from her son and fears the worst. She was standing in front of an Orlando hospital just down the street from Pulse.

She id, “These are nonsensical killings of our children. They’re killing our babies!”

She said her son’s friend made it out alive by hiding in the bathroom and running out as bullets were flying.

Also, on Sunday morning Facebook added a “Facebook Safety Check” for people to find out whether friends and family have tagged themselves as safe. The social network is using the heading “The Shooting in Orlando, Florida.”

It is Facebook’s way of allowing its users who live near the scene of a major crisis to notify people that they’re OK.
