WASHINGTON (CBSDC) - The man police were looking for in connection with Sunday’s Metrobus shooting that killed a woman and injured her young child has taken his own life, sources tell WNEW.

Twenty-year-old Selina Brown was shot and killed while boarding a Metrobus in the 1700 block of Minnesota Avenue around 5:40 p.m. on Sunday. Police had issued a warrant for 27-year-old Javon Foster, the victim’s boyfriend.

Brown’s stepfather tells WNEW he received a call that Foster killed himself in New York City. He was the prime suspect in the shooting that also hospitalized their 23-month-old child, who was grazed by a bullet.

The child is in stable condition.

D.C. Police Chief Cathy Lanier says the shooter came up behind them and opened fire.

Brown was unconscious and unresponsive in the doorway of the Metrobus when police arrived. The body was taken to a medical examiner a short time later for an autopsy.
