An unidentified transgender woman died early Friday morning after being fatally stabbed about 8:15 Thursday night at a Metro bus stop in the 4900 block of East Capitol Street, N.E., D.C. police said.

According to a police statement, the department’s Homicide Branch is investigating the incident. As of Friday afternoon, homicide detectives had not been able to identify the victim.

Earline Budd, an official with the transgender services and advocacy group Transgender Health Empowerment, said investigators planned to bring one or more photos of the victim to the THC office with the hope that someone there could identify the victim.

The police statement says a citizen flagged down a Metro Transit Police officer about 8:13 p.m. Thursday to report an assault at a bus stop.

“Upon arrival, the officer located a transgender female who was unconscious and unresponsive suffering from a stab wound,” the statement says. “Units from the Sixth District and D.C. Fire and Emergency Medical Services personnel responded to the scene. The victim was transported to a local hospital and was admitted in critical condition,” the statement says.

“On Friday, Feb. 3, 2012, at 2:35 a.m., the victim was pronounced dead. The decedent has not been identified at this time,” says the statement.

Captain Edward Delgado, director of the department’s Special Liaison Unit, which oversees the Gay and Lesbian Liaison Unit, told LGBT activists in an email Thursday night that police have a partial description of a male suspect in the case.

“Apparently there was a fight with the knife involved,” Delgado said in his email. “An adult female (transgendered) was stabbed at least once to the head by a black male wearing [a] heavy dark coat with [a] grey striped hat.”

The separate statement released by the Metropolitan Police Department’s public information office says police offer a reward of up to $25,000 to anyone that provides information leading to the arrest and conviction of the person or persons wanted for any homicide committed in D.C.

Anyone with information is asked to call police at 202-272-9099. Anonymous information can be submitted to the department’s “TEXT TIP LINE” by text messaging 50411, the police statement says.

Two transgender women were murdered in the city in separate incidents in 2011. Both cases remain unsolved.
