The ex-Dallas police officer who fatally shot Botham Jean in his apartment in September was indicted by a grand jury today on a murder charge, according to a clerk with the Dallas County court.

Botham Jean, a 26-year-old accountant and native of the Caribbean island of St. Lucia, was killed on September 6 as he watched a football game in his apartment. Guyger, Jean’s downstairs neighbor, told investigators she mistook Jean’s apartment for her own and thought she’d encountered an intruder. She has since been fired from the department.

Jean’s family has filed a lawsuit against Guyger and the city of Dallas. Guyger was arrested on a manslaughter charge three days after the Sept. 6 shooting.

If convicted of murder, Guyger could receive five years to life in prison.
