Rewards totaling $100,000 were available today for information leading to the gunman who shot a Los Angeles school police officer near El Camino Real High School in Woodland Hills.

The Los Angeles City Council put up a $75,000 reward.

The following organizations each contributed $5,000 to the reward effort:

-- the Los Angeles Police Protective League, the union representing rank-and-file LAPD officers;

-- the Los Angeles School Police Officers Association;

-- and the Los Angeles Retired Fire and Police Association.

David Gold, founder of the 99 Cents Only stores, put up $9,999.99, and City Councilman Dennis Zine took a penny out of his pocket and made it an even $10,000.

Officer Jeff Stenroos was shot once in the chest about 11:40 a.m. Wednesday, but his protective vest saved him from serious injury. He was released from a Northridge hospital about seven hours after the shooting and was recovering at home.

Investigators described the gunman as being in his mid- to late-40s, about 5 feet 10 inches tall, with long grayish hair pulled into a ponytail. He was wearing blue jeans and a dark bomber jacket and armed with a semiautomatic handgun.

Authorities locked down nine schools and cordoned off neighborhoods as hundreds of officers searched for the shooter into the night.

A police sketch of the gunman was released Thursday.
