Many in the Atlanta LGBT communities are concerned about possible hate crimes against them after two separate incidents happened in the span of just days, one of them involving a homicide.

One of those attacks was during a Saturday rally in the heart of Midtown Atlanta. Marchers had gathered to protest against President Trump's decision to ban people who are transgender from serving in the military.

Charlie Stadtlander had just lifted his smartphone in order to Facebook Live the march, when he says a man came out of nowhere and attacked him.

"He kicked me," Stadtlander told 11Alive on Tuesday, "yelled a barrage of gay slurs at all of us, told us he had a gun, reached in his waistband, showed what to me appeared to be a gun, and told us he was going to kill all of us."

Atlanta Police arrested Wilford Hardnett, 21, and charged him with aggravated assault and armed robbery. Stadtlander said Hardnett later apologized to him, but Stadtlander said everyone in the crowd definitely feared for their lives at the time of the attack.

Police took Hardnett to the Grady Hospital Detention Center after, they say, he threatened to kill himself.

But that's not the only alleged crime police are investigating. In College Park on Monday, at the South Hampton Estates on Godby Road, someone shot a trans woman multiple times.

Tee Tee Dangerfield, 32, was alive when first responders arrived. They found her sitting inside her car. But she was unable to speak. She died later at the hospital. College Park Police Maj. Lance Patterson said Dangerfield did not live at that apartment and they still don't have a motive.

“From the concern that it may have been a hate crime, we don’t know that, yet," Patterson said. "We don’t have anything in our investigation, so far, that leads us to believe that it was, but, again, we don’t know." Maj. Patterson said detectives will continue to investigate the motive--whether it was a hate crime or something else--as they try to identify and find a suspect.

According to the Human Rights Campaign, in 2016 there were 22 known homicides of transgender people across the country -- the most ever recorded; so far this year, there have already been 15.
