Witnesses of a road rage incident on a San Diego highway in which a Navy officer was killed last week shared video taken just moments before the crash.

In the video captured on a mobile phone, a dark-colored car can be seen driving closely behind a motorcycle.

William Touch told NBC 7 he was trying to follow the two vehicles and witnessed the vehicle "sideswiping" the motorcycle three times.

"Her front bumper was literally touching the bike itself," Touch said Sunday. "She stayed right behind him and I guess clips the back tire and I guess shakes a little bit."

California Highway Patrol Officers arrested driver Darla Jackson Friday and charged her with one count of murder for the May 28 collision that killed Zachary Buob, an active duty Chief Petty Officer in the Navy's special operations.

Jackson, 26, was driving a black Nissan Altima northbound on Interstate 5 near E Street in Chula Vista at around 5:30 p.m. Thursday.

Jackson and a man on a red Ducati motorcycle got into some type of disagreement on the roadway, officials said.

After the two drivers transitioned from I-5 to eastbound State Route 54 and passed National City Boulevard, Jackson hit the Ducati from behind and ran over the rider, CHP officers said.

The motorcyclist, identified by friends as 39-year-old Zachary Buob, a Santee resident, died about an hour later at a hospital.

"Still can't believe that this happened to such a good guy in such an evil act," said Donny McCowan. "It happened to such a good individual. He's one of the greatest guys I know at the command and he's really going to be missed."

Buob's death brought bikers and service members from across the state to ride in honor of their brother.

They rode from Mission Valley mall to the site of the crash where a memorial of flowers and flags grows.



"How he left he didn't deserve it," said family friend Chad Braun. "He served his country and he was here home doing what he loved and he was free and it's sad he went the way he did.



"It was unexpected and it shouldn't have happened."
