A week after being fatally shot during a traffic stop, California Highway Patrol Officer Kenyon Youngstrom continues to save others.

Youngstrom died Sept. 5 after being taken off life support at John Muir Medical Center in Walnut Creek, where he had been listed in critical condition after being shot multiple times on Interstate 680 in Alamo a day earlier, said CHP Commissioner Joe Farrow.

Since his death, Youngstrom has given the gift of life to four individuals through organ and tissue donations, including a 29-year-old Bay Area mother who had spent the last three years on a transplant waiting list, the CHP reported Tuesday. The woman received his left kidney and pancreas, while his other kidney was given to a 52-year-old Bay Area woman who had been on a transplant list since 2002.

Along with these two women, a 50-year-old Southern California husband and father of four children received a new heart, and a 63-year-old Bay Area woman was given a new liver, authorities said.

Surgeons and operating-room personnel observed a moment of silence during the surgery to recover Youngstrom”s organs, and a remembrance from his family was read, in which they recalled him as “a loving father and husband who ”put God, his wife and his children first,” ” officials said.

Youngstrom, a Cordelia resident, is survived by his wife, Karen, and four children, who were present at a bell-knelling ceremony honoring the officer on Sept. 6 at the CHP Academy in West Sacramento.

Hundreds of uniformed CHP officers and cadets turned out for the somber ceremony during which Youngstrom”s name was read and a memorial bell was tolled.

“He radiated joy and genuine care for all around him. His service and dedication were unwavering,” officials said in a statement.

Farrow called the shooting “devastating,” adding that “it scars and wounds the entire organization.”

His death marks the 223rd CHP officer to be killed in the line of duty, Farrow said.

Youngstrom was assisting another officer when he flagged down a passing Jeep driven by 36-year-old Christopher Boone Lacy and directed him to pull in behind his patrol car around 8:20 a.m., Farrow said. Youngstrom was shot in the head seconds after contacting Lacy, who in turn was shot and killed by another CHP officer who had requested Youngstrom to stop the vehicle after observing a “minor infraction” by Lacy.

The shootings were captured by the officer”s onboard dash camera, which was turned over to the Contra Costa Sheriff”s Office, which is conducting the investigation.

Funeral arrangements have been finalized, with Youngstrom”s service taking place at 10 a.m. Thursday at the Mission Church in Vacaville, 6391 Leisure Town Road, with a reception following in The Mission gymnasium. The family has requested privacy, officials said, but understands the need and desire of the public to share in mourning Youngstrom.

Accounts have been set up at two Bay Area banks to benefit the Youngstrom family.

Donations for the Kenyon Marc Youngstrom Children”s Benefit Memorial fund will be accepted by tellers at any Wells Fargo Bank branch, while contributions in the officer”s name will be added to a trust account in his name at any Mechanics Bank branch. Checks should be made payable to “For Benefit of Officer Kenyon Youngstrom,” and can also be mailed to Mechanics Bank, 1350 N. Main St., Walnut Creek, 94596. Wire transfers can be sent to routing number 121102036 and addressed “For Officer Kenyon Youngstrom.”
