According to TMZ.com, “The killer in the Orlando nightclub slaughter is 29-year-old Omar Mateen. TMZ has done a records search and found he held a Florida security officer license and a state firearms license.
“The NYPD tells TMZ, Mateen has no association with the department, and that the shirts he was photographed in were unofficial garments that could be purchased at any store.
“Mateen’s father told NBC News, ‘This has nothing to do with religion.’ He says his son became angry after seeing two men kissing a few months ago in Miami, and he speculates that could have triggered his decision to kill.”
