An Orlando man originally from Detroit is among 49 people killed in Sunday's shooting at a gay nightclub, according to the city of Orlando and WXYZ-TV (Channel 7).

Christopher Andrew Leinonen, 32, moved from Detroit to Orlando years ago, according to WXYZ.

His mother, Christine Leinonen, told ABC News that she's proud of her son and had last spoken with him Saturday evening. The shooting at Pulse nightclub is the deadliest in U.S. history, with 50 dead and about 53 injured.

FBI Director James Comey said gunman Omar Mateen, 29, appears to have been a religious radical who voiced support for multiple Islamic terror groups, USA TODAY reports. The city of Orlando website has published a list of confirmed victims.

Christine Leinonen told ABC News her son established the gay straight alliance at his high school and received a humanitarian award for his effort.

She was one of many parents hearing their fears confirmed as officials released the identities of victims. On Sunday night, Mina Justice learned that her son, Eddie Jamoldroy Justice, 30, had died after sending her texts telling her he loved her and asking for help, USA TODAY said.
