BOSTON (WHDH) - Massachusetts State Police say that in a conference call with federal law enforcement, they learned that the Orlando nightclub gunman pledged allegiance to ISIS and referenced the Tsarnaev brothers.
The Tsarnaevs carried out the Boston Marathon bombings that killed three people. They also murdered MIT Police officer Sean Collier.
The shooter in Orlando has been identified as Omar Mateen of Florida.
50 people were killed in nightlcub attack in Orlando early Sunday morning.
The shooting is the largest mass shooting in the history of the United States.
The FBI says the shooter was known to the agency before the incident and had been looked at by agents within the last few years.
The official says the matter for which Mateen came under investigation was “open and closed pretty quickly.”
Other details about the matter weren’t immediately available.
Mateen was a security guard with G4S. In a 2012 newsletter, the firm identified him as working in West Palm Beach.
In a statement sent to the Palm Beach Post, the security company confirmed his employment.
“We are shocked and saddened by the tragic event that occurred at the Orlando nightclub. We can confirm that Omar Mateen had been employed with G4S since September 10, 2007. We are cooperating fully with all law enforcement authorities, including the FBI, as they conduct their investigation. Our thoughts and prayers are with all of the friends, families and people affected by this unspeakable tragedy.”
