The money for the $1-million reward for information leading to the capture of ex-LAPD Officer Christopher Jordan Dorner was contributed by 29 donors, according to a list released by Los Angeles Police Department officials.

Mayor Antonio Villaraigosa confirmed the reward at a Sunday afternoon news conference in which he insisted Dorner will be found.

“We will not tolerate a killer targeting our officers and our families, targeting innocent people in this city and this region,” Villaraigosa said.

Police officers associations and law enforcement departments in Long Beach, San Diego, Irvine and Riverside are among the donors to the reward. The list also includes USC President Max Nikias, the Dodgers, AEG, the Safer CA Foundation, the Orange County Crimestoppers and six anonymous donors.

"This is the largest local award ever offered, to our knowledge," said LAPD Chief Charlie Beck. "This is not about capturing a fleeing suspect, this is about preventing a future crime -- likely a murder."

Beck said the idea to offer a massive award first came from his wife on Saturday. Within 24 hours, the $1 million had been raised, with the police chief and mayor receiving unsolicited calls from donors.

"For those of you that question how so much money was put together: it was amazingly, amazingly easy," Beck said. "When we reached out to members of this community, they gave immediately."

A massive manhunt for Dorner began last week after the 33-year-old Navy veteran allegedly began a deadly campaign that has left an Irvine couple and a Riverside police officer dead. Dorner is believed to be upset over his firing from the department in 2009.

The frustrating search for Dorner has spanned from Riverside to Corona to Big Bear to Point Loma in San Diego. There have been numerous false starts, but officials say the heightened publicity has not brought them closer to making an arrest.

Dorner's Nissan Titan pickup was found Thursday morning engulfed in flames on a mountain road in the Big Bear area, and law enforcement officials have since focused their search efforts there.

Officials said Sunday the search in Big Bear was winding down.
