UPLAND, Calif. — A dramatic motorcycle pursuit concluded with a severe collision on a Southern California freeway Monday afternoon. The chase followed a tragic incident where a sheriff’s deputy was fatally shot.

Warning: The video above contains graphic content that may be disturbing to some viewers.

The sequence of events began when deputies from the San Bernardino County Sheriff’s Department responded to a reported domestic violence incident in Rancho Cucamonga. The call involved a man allegedly armed and threatening a woman.

According to the sheriff’s department, the deputies were met with gunfire upon their arrival. Deputy Andrew Nunez was critically injured by a gunshot to the head.

Despite being swiftly transported to the hospital, Nunez tragically succumbed to his injuries, as confirmed by the authorities.

Subsequently, the suspect attempted to evade capture by fleeing on a motorcycle, leading to a high-speed chase along the 210 Freeway.

After the suspect opened fire, he hopped on a motorcycle, sparking a high-speed chase that ended in a major crash on the 210 Freeway, officials confirmed.

All eastbound lanes were shut down and a SigAlert was issued between Mountain and Campus avenues.

AIR7 video from our sister station, ABC7 Eyewitness News in Los Angeles, showed traffic backed up for miles as the traffic was at a standstill during peak rush hour traffic at 3 p.m. local time.

During an afternoon press conference, Sheriff Shannon Dicus confirmed that an off-duty sheriff’s deputy conducted a “legal intervention” by striking the suspect on the motorcycle.

That’s when the suspect was launched into the air and landed on the road.

Officers quickly ran out of their patrol cars and rushed to handcuff him.

The suspect was sitting up and conscious as authorities rendered aid. He was airlifted to an area hospital in stable condition.

Authorities are working to forensically positively identify the suspect and are waiting to interview him.

The suspect’s name was not immediately released.

Video from the hospital Nunez was taken to shows law enforcement officers gathered outside the emergency room. An Eyewitness News crew at the scene also spotted what appeared to be family members arriving at the hospital.

Sheriff Shannon Dicus said Nunez leaves behind a wife, a 2-year-old daughter, a mother and four brothers and sisters. His wife was also expecting, the sheriff said.

Dicus said Nunez had been with the San Bernardino County Sheriff’s Department for six years and served the Rancho Cucamonga community for five years. He described Nunez as a “wonderful father” and “wonderful deputy sheriff.”
