Orlando Shooter drank alone at Nightclub before attack

Alleged Orlando mass killer, Omar Mateen 

Omar Mateen, 29, the man suspected to be responsible for the Sunday morning shooting and killing of 49 people in a gay club in Orlando, US, is believed to have visited the club a dozen times in the past three years. According to witness, he usually drink alone.

The son of an Afghanistan immigrant pledged allegiance to ISIS after the shooting, in a 911 phone call.

Maybe, it is high time the authorities keep a close tab on people who exhibit anit-social behaviour.
