A transgender youth leader was charged with murder Monday in the fatal stabbing of her boyfriend in Walnut Creek, a prosecutor said.

Akira Tajah Jackson, 24, of Oakland was also charged with an enhancement for using a large kitchen knife to kill 56-year-old Alan Gray in his home on Santa Rita Drive at about 9:20 a.m. Thursday.

Born David Gavin, Jackson has been living as a woman for five years and met Gray about a year and a half ago while she was dancing at Diva's nightclub in San Francisco, said Contra Costa County prosecutor Barry Grove.

Gray was aware of Jackson's transgender identity, Grove said.

Gray called 911 shortly before he was killed, saying Jackson had assaulted him, the prosecutor said.

Responding officers found Gray outside his home, Grove said. He had been stabbed in the chest, his nose was broken and his face was bruised. He was pronounced dead at John Muir Medical Center in Walnut Creek.

Jackson was arrested at the scene.

Authorities said the slaying was the result of a domestic dispute, but declined to say what exactly led up to the killing.

Jackson has worked as a youth program specialist for T-LISH, Transgender Ladies Initiating Sisterhood, at the Asian and Pacific Islander Wellness Center in San Francisco.

She is being held in lieu of $1 million bail at Contra Costa County Jail in Martinez.
