BART officials announced via Twitter Monday evening that a press conference would be held to discuss the arrest of the suspect in the killing of Nia Wilson at the MacArthur station on Sunday night.

Earlier on Monday, authorities identified John Lee Cowell as the suspect wanted for fatally stabbing Wilson, 18, and wounding her sister on Sunday night. 

Cowell, 27, boarded a train in Concord, the same station where Nia Wilson, the victim, and her sister got on the train bound for Warm Springs, according to police. The three exited the train in Oakland's MacArthur station, where the stabbing attack occurred around 9:30 pm. 

Police were already at the station when Cowell allegedly knifed the two women, but he evaded capture and slipped into the surrounding area. Authorities did not initially  establish a motive for the attack. 

Officials said that a knife and other evidence had been gathered from the station. 

On Monday, authorities released surveillance footage of Cowell from the night of the attack as well as a previous mug shot and an image from a recent encounter with an officer that was recorded on a body camera.

While discussing Wilson's death, BART officials revealed that there have also been two other apparent killings stemming from violent incidents on the transit system in the last five days.
