Police say a man held 10 people hostage inside a California office building before the FBI shot and killed him, bringing a more than 15-hour standoff to an end. The Bakersfield Police Department says the hostages were found unharmed early Wednesday inside the downtown Bakersfield building that houses a bank and a school district office. The standoff began Tuesday afternoon when officers responded to a call of a bomb threat. Authorities say the suspect was an Army veteran who was dishonorably discharged, had a history of trouble with law enforcement and was a registered sex offender.
