Daily Mail released the footage from the apartment where the killer responsible for the massacre of 50 people inside gay Orlando nightclub Pulse had been living and plotting out his horrific attack.

Omar Mateen had been living in Apartment 107 at the Woodland Condominium in Fort Pierce since he was divorced from wife Sitora Yusufiy in 2011. He was living there with the woman believed to be his current wife and mother of their three-year-old son, Noor Zahi Salman.

The walls of the apartment are adorned with photos of Mateen's three-year-old son. Loads of toys including a Spiderman bicycle, toy trucks and Mickey Mouse posters can be seen throughout the two-bedroom home.
What looks like a ceremonial sword sits proudly by the TV set in the living room and workout equipment sits in a corner. Mateen was known to be obsessed with his physique and had taken steroids.

There is a Mickey and Minnie Mouse calendar marked 'D-Day, 10 pm' on June 7th. The real D-Day is June 6th leaving open the question was Mateen planning something sooner than the June 12 morning of horror. Or was it just marked for Ramadan, the Muslim holy holiday.

Apartments in the building rent for between $600 and $1,000 at the property. Daily Mail Online learned exclusively that Mateen was earning $1,600 a month from his job at G4S Secure Solutions in Jupiter.

Mateen earned an associate's degree in criminal justice from Indian River State College in Fort Pierce, and expressed interest in joining the police force.

Instead, he worked as a security officer, a fact that comforted other members of the Islamic Center of Fort Pierce where he worshipped, Syed Shafeeq Rahman, the head of he mosque, said.

Sitora Yusufiy, Omar Mateen's first wife, described how he "seemed like a normal human being" at first.

Following a brief romance after the two met online, the pair married in 2009 and moved into the two-bedroom home in Fort Pierce.

"After a few months he started to beat me," she said. "He was mentally unstable… he was obviously disturbed. I know he had a history of [taking] steroids.

"He was not a stable person. He would just come home and start beating me up because the laundry wasn’t finished or something like that."

Yusufiy said that Mateen owned a gun during their marriage, was "short tempered" and would express "hate towards things". She would not reveal if he had any homophobic views.
