Los Angeles Deputy Shot

People gather for a vigil for Los Angeles County Sheriff's Deputy Ryan Clinkunbroomer at the Palmdale Sheriff's Station, Sunday, Sept. 17, after the training officer was shot and killed in his patrol car at an intersection a day earlier, in Palmdale, Calif.

PALMDALE, Calif.  — A “person of interest” was detained in the investigation of the fatal shooting of a Los Angeles County sheriff's deputy, a department spokesperson said early Monday.

There was no additional information about the detained person but officials planned to hold a news conference later in the morning, said law enforcement technician Kimberly Herrera at the sheriff's information bureau.

Deputy Ryan Clinkunbroomer, 30, was shot as he sat in his patrol car at an intersection and died at a hospital after being found unconscious in the vehicle around 6 p.m. Saturday in the city of Palmdale, according to Los Angeles County Sheriff Robert Luna.

“Without warning, he was murdered while serving our community,” an emotional Luna said at a Sunday news conference during which he urged any potential witnesses to contact detectives. A $250,000 reward was offered for information.

The department released grainy surveillance video of a dark-colored sedan that pulled alongside the patrol car in the moments before the shooting. Luna said investigators believe the “vehicle of interest” is a gray Toyota Corolla manufactured between 2006 and 2012.

Clinkunbroomer had just left the sheriff's station in Palmdale, a city of more than 167,000 residents in the high desert of northern Los Angeles County. A “good Samaritan” spotted him and alerted station personnel.

The sheriff said Clinkunbroomer was a third-generation deputy, following his father and grandfather into the department, and had been assigned to the Palmdale station since July 2018. He was also newly engaged.

“He had so much ahead of him,” Luna said.

California Gov. Gavin Newsom called the killing “horrific, unconscionable and shocking.” He ordered flags at the state capitol flown at half-staff in honor of Clinkunbroomer.

“In this time of mourning, we honor this legacy and send our deepest sympathies to Deputy Clinkunbroomer’s fiancée, his loved ones, and the men and women of the Los Angeles County Sheriff’s Department,” Newsom said in a statement Sunday. “Deputy Clinkunbroomer’s devotion to community and country will never be forgotten.”

The Association for Los Angeles Deputy Sheriffs, the deputies' union, said Clinkunbroomer became engaged to be married four days before he was killed.

“Deputy Sheriff Ryan Clinkunbroomer and his family are an integral part of the very essence of the Los Angeles Sheriff’s Department, and this heart-wrenching murder cuts to the very core of our being,” ALADS President Richard Pippin said in a statement.

Deputy William Warner, who trained Clinkunbroomer, told the Los Angeles Times his determination to follow in his father‘s and grandfather’s footsteps was evident in his work ethic.

“He just wanted to do the best that he could do,” Warner said, “and do his small part to make a difference in the best way that he could.”

A huge crowd attended a vigil for the deputy Sunday evening outside the Palmdale station.
