The body of the Pulse shooter has been released from the Orange County Medical Examiner's Office, authorities said on Monday.

County officials said Monday that the medical examiner was no longer in possession of 29-year-old Omar Mateen's body. At the request of the FBI, no further information is available regarding Mateen's autopsy report, who the body was released to or when the body was released.

The medical examiner previously said his office kept Mateen's body separate from the 49 victims who died when Mateen opened fire on patrons at Pulse, a gay nightclub in Orlando, in the early morning hours of June 12.

In the wake of the shooting, 53 people were found injured and police identified 49 people who were killed inside the club.

The nightclub was packed with people when Mateen began firing an assault rifle.

According to transcripts released by the FBI, no shots were fired from 2:02 a.m., when gunfire was first reported at the club, until the final shootout with police more than three hours later. In a call made at 2:35 a.m. June 12, Mateen spoke with a 911 operator for about 50 seconds.

"In the name of God the merciful, the beneficial (words in Arabic)," Mateen told the operator while calling from inside the club. He went on to claim credit for the shootings.

At a news conference Monday, Orlando police said officers were rescuing people from the club during the three-hour period when no shots were being fired.

Mateen was killed during the shootout with authorities.
