A former Fort Pierce police officer who once worked with 29-year-old Omar Mateen, the assailant in an Orlando nightclub shooting that left at least 50 dead, said he was "unhinged and unstable."
Daniel Gilroy said he worked the 7 a.m. to 3 p.m. shift with G4S Security at the south gate at PGA Village for several months in 2014-15. Mateen took over from him for a 3 to 11 p.m. shift.
Gilroy, a former Fort Pierce police officer, said Mateen frequently made homophobic and racial comments. Gilroy said he complained to his employer several times but it did nothing because he was Muslim. Gilroy quit after he said Mateen began stalking him via multiple text messages — 20 or 30 a day. He also sent Gilroy 13 to 15 phone messages a day, he said.
