“Extraordinary cooperation among multiple law enforcement agencies led to these arrests and a small measure of justice for the true victims,” said Contra Costa Sheriff David Livingston. “Additionally, evidence shows two of the deceased persons inside the house were themselves armed, which may have played a role in this tragedy. We look forward to providing more information in the coming days.”
