Motorcyclist wanted in connection with California deputy's killing is stopped by off-duty officer during high-speed chase

An off-duty sheriff's deputy jumped into action and brought an end to a high-speed chase of a motorcyclist wanted in connection with the killing of a fellow deputy Monday afternoon in Southern California.

An off-duty sheriff's deputy jumped into action and brought an end to a high-speed chase of a motorcyclist wanted in connection with the killing of a fellow deputy Monday afternoon in Southern California.

Sheriff’s officials suspect the motorcyclist was involved in the shooting of a San Bernardino County sheriff’s deputy who responded to a report of a man threatening a woman with a gun in the city of Rancho Cucamonga, about 45 miles east of downtown Los Angeles, sheriff’s officials said.

The deputy, six-year-veteran Andrew Nunez, 28, father of a 2-year-old daughter and expecting another child, was shot in the head just after 12:30 p.m. after arriving at the scene and later died at a hospital, sheriff’s officials and the office of California Gov. Gavin Newsom said.

“Deputies arrived and were immediately shot at by the suspect,” the sheriff's department said in an earlier statement.

The incident triggered a high-speed chase that ended only when an off-duty deputy drove a Toyota Camry, which the department described in a statement as an “unmarked Sheriff’s Department vehicle,” into the bike’s path on the 210 Freeway in the city of Upland at about 1:35 p.m., Sheriff Shannon D. Dicus said at a news conference.
