SAN DIEGO — Scores of bikers roared their engines Tuesday in memory of a chief petty officer in special operations for the U.S. Navy, who was killed in an alleged road rage incident on May 29.

Zacharias Buob, 39, was remembered as a prankster who loved his country and riding motorcycles.

“I would’ve trusted Zach to teach my son to ride,” said Diane Gregor, Buob’s ex-girlfriend.

Darla Renee Jackson, 25, pleaded not guilty to a murder charge and faces 15 years to life in prison if convicted, prosecutors said.

Jackson was heading north on Interstate 5 in Chula Vista when she got angry with Buob riding a red Ducati motorcycle near her Nissan Altima about 5:30 p.m. Thursday, according to the California Highway Patrol. The rolling altercation continued as the two passed through National City and merged onto eastbound State Route 54, CHP public affairs Officer Jake Sanchez said.

Near Sweetwater Road, Jackson allegedly rammed the motorcycle from behind and then ran over Buob.   Paramedics took Buob to a hospital, where he was pronounced dead. The reason for the roadway dispute was unclear.

Authorities asked any witnesses to the crash or what led up to it to call CHP traffic investigator Brad Clinkscales at 619-220-5492.

“Motorcycles aren’t always saints and neither are drivers, but no one should ever use their car as a lethal weapon,” said Gary Klopp, a close friend of Buob.

Jackson is being held on $1 million bail and will return to court on July 10.

According to a Facebook memorial page for Buob, in lieu of flowers or other forms of gifts, the family requests donations In Memory of Chief Petty Officer Zacharias Buob to: Navy SEAL Foundation, 1619 D Street, Virginia Beach, VA 23459
