MARTINEZ -- James Collin, the 62-year-old man suspected of killing his longtime girlfriend at their home in Orinda on Tuesday, is being held on $1 million bail at the County Detention Center.
Investigators offered little new information about the crime Wednesday, a day after Collin went to a neighbor's house and got him to call 911, leading police to the 51-year-old woman's body in the kitchen of the home they shared on the 600 block of Moraga Way. A jail employee confirmed Collin's status in custody.
The cause of death is "blunt force and sharp force injury of head," according to the sheriff's office. An autopsy was conducted Wednesday morning. The woman's name is not being released pending notification of family.
Police said Tuesday that they had recovered the weapon used in the slaying on a property adjacent to Collin's home but would not identify it. A law enforcement source had previously told this newspaper that it was a machete.
A spokesperson for the Contra Costa District Attorney's Office said Wednesday afternoon that prosecutors are reviewing the case, but no decision on charges has been made yet.
Collin has "a history of domestic violence," Orinda police Chief Jeff Jennings said Tuesday. Jennings said that Collin, who was "lucid and calm" when taken into custody, had made statements that he had killed the woman.
Collin "had stuff on him that looked like he was in a tussle" when he was arrested, Jennings said
No one else was injured in the incident, though the 90-year-old neighbor who called police was taken to John Muir Medical Center for evaluation.
Detectives with the Contra Costa County Sheriff's Office are investigating the case.
The killing is believed to be the first in Orinda since 2002, when Susan Polk fatally stabbed her 70-year-old husband, Felix. Polk was convicted of murder in 2006 and sentenced to 16 years to life in prison.
Anyone with any information on this case is asked to call the sheriff's office at 925-313-2600.
