SAN DIEGO - A San Diego police officer will be remembered Tuesday at the McDonald's where he performed his last act of kindness before being gunned down in his patrol car.

The San Diego Police Officers Association and the operator of a City Heights McDonald'swill hold a 12-hour fundraiser and "family fun day'' in honor of Officer Jeremy Henwood. Between 7 a.m. and 7 p.m., a portion of the proceeds from purchases at the fast-food eatery at 3879 Fairmount Ave. will go to the SDPOA's Widows and Orphans Fund. The event also will feature appearances by McGruff the Crime Dog, face painting and historic police vehicles on display, according to the SDPOA.

The event will take place at the restaurant, where the officer stopped to pick up dinner just prior to the slaying.

Henwood was also honored Monday, one year after he was shot and killed, for donating his organs, which ultimately saved the lives of two mothers.

A portrait of Henwood was surrounded by roses Monday morning during a service that focused on how his generous spirit lives on through the donation of his organs.

On August 6, 2011, Henwood was sitting at a stoplight in City Heights when Dejon White, 23, drove up next to him and shot him in the head with a .12 guage shotgun for no apparent reason, investigators said. Henwood later died of the gunshot wound at the hospital.

The former Marine's organs saved the lives of two mothers who had been on dialysis for seven years after suffering kidney failure.

"Obviously, I don't know him in life. I know him as donor - an incredible man. He touched so many lives," said Sharon Ross, spokeswoman for a  life-saving program. "I think the fact that he returned from three combat duties, signed up to be a donor, wanted to be a police officer that's a testament of a hero in life and in death."

Officers reflected on his generosity and selflessness.

"He was always giving, not surprising that he was willing to donate parts of his body to let someone else live on. His legacy is still living on," Officer Daniel Craft said. "He was a great person, big heart, best example I can give you is McDonalds."

Moments before Henwood was shot, Henwood's generosity at a nearby McDonalds changed the life of a little boy.

Surveillance videos show Henwood buying lunch, then a 13-year-old Daveon Scott asked him for 10 cents to buy a cookie - Henwood bought him three.

"He changed my life a lot. He gave me inspiration to work harder in life," said Scott, who reflected on having a discussion with Henwood about focusing on future goals.
