MARTINEZ -- A woman who was assaulted and killed by a man she was dating has been identified and the man is being held on suspicion of murder following the Saturday night slaying on the steps of the city's Chamber of Commerce office.
Witnesses told police the assailant, later identified as Jason Castillo, 25, of Concord, hit Cecelia Kingsley, 47, of Martinez and then walked away from the chamber offices across the railroad tracks toward downtown. The chamber offices were closed at the time.
Police arrested Castillo a short time later walking on Ferry Street. He is being held at County Jail in Martinez on $1 million bail and the district attorney is expected to review the case this week.
The chamber shares a building with the Amtrak station on Marina Vista Avenue. Officers first responded to the station but later determined the attack occurred on the chamber steps about 7:25 p.m., said Martinez Police Lt. Jon Sylvia.
An autopsy to determine the cause of death was scheduled for Monday, Sylvia said. Investigators are still looking into the couple's relationship and have not said what sparked the attack.
Witnesses reported the two had a fight before the attack, police said. The original police report also says a woman in her 20s was seen walking away from the offices with Castillo after the attack. Information on that person was not released.
The death was the first homicide reported this year in Martinez; no homicides
