A Baton Rouge woman accused in 2012 of stealing a bicycle from a man she shot, riding several blocks and fatally shooting another man has pleaded guilty to manslaughter and attempted murder charges in return for a 28-year prison term.

Tameka Johnson, 33, faced an automatic sentence of life in prison if convicted this week of second-degree murder in the Feb. 16, 2012, killing of Tyrone Clark, 55. He was shot in the head in the 200 block of West Polk Street.

Johnson also pleaded guilty Tuesday before state District Judge Chip Moore to attempted second-degree murder in the wounding of a 51-year-old man from whom she stole a bike. He was shot in the shoulder outside a home in the 200 block of West Grant Street.

The woman and the two men had argued earlier in the day, police have said.

Prosecutor Larry McAlpine said Wednesday that Johnson has serious mental issues for which she will receive treatment while incarcerated.
