WATCH: New video shows moments before transgender woman’s death 

Police hope new surveillance video will lead them to the person who shot and killed a transgender woman outside a College Park apartment.

The video, obtained by Channel 2 Action News, shows Troy “Tee Tee” Dangerfield walking inside the 50 Yard Line sports bar about 1 a.m. July 31.

Police told the television station she had drinks with a friend and left the bar about two hours later.

Dangerfield, 32, was shot about 4:20 a.m. — nearly an hour and a half later — as she sat in her car outside the South Hampton Estates in the 3100 block of Godby Road, College Park police said. 

Medics rushed her to the hospital, but she died on the way there.

The video, police said, is key to helping them solve the case because it establishes a timeline leading up to Dangerfield’s death. 

While investigators have not uncovered anything that suggests gender played a role in the deadly shooting, relatives of the woman are not ready to rule it out.

According to the nation’s largest lesbian, gay, transgender and queer civil rights organization, at least 22 transgender people were killed in the United States in 2016, the most recorded by Human Rights Campaign.

Dangerfield’s name was added to the 2017 edition of that list. She is No. 16.

Ava Le’Ray Barrin, 17, was shot during a June 25 fight in the parking lot of an Athens apartment complex. Jalen Breon Brown was charged with murder in connection with Barrin’s death.
