RICHMOND  (AP) — Authorities have released the name of a man who was shot to death outside a Bay Area Rapid Transit station last week, but police are still looking for one or two men believed to be the shooters.

Officials say 34-year-old Raymond Harris was shot and killed in a barrage of gunfire outside the Richmond BART station around 6:22 p.m. Thursday.

BART police say witnesses reported seeing one or two men running from the station, but no arrests have made.

After the incident, BART police Deputy Chief Ben Fairow said the shooting was sparked after "some type of altercation."

The fatal shooting was the third homicide of the year in Richmond. In 2012 the city recorded its lowest number of slayings in 11 years, with 18 people killed.
