A friend of the driver killed in a confrontation at the entrance to the National Security Agency said the individual identified as transgender and was a sex worker in Baltimore.

Twenty-seven-year-old Ricky Shawatza Hall was killed Monday when NSA police opened fire on a stolen car that then crashed into a police vehicle. A passenger was wounded, as was an officer.

Kayla Brooks, who works at a transgender outreach program in Baltimore, says she last saw Hall on Sunday. Brooks says Hall "seemed high and was looking for a date" while walking up and down a Baltimore strip known as a hotspot for sex work.

Brooks says Hall went by the name Mya and was nice and friendly but "very troubled."
