Los Angeles authorities have detained a person of interest in connection with the murder of a county sheriff's deputy who was ambushed and fatally shot at a traffic light on Saturday, the sheriff's office said on Monday.

A reward of $250,000 was offered on Sunday for any information regarding the shooting of Ryan Clinkunbroomer, 30, as he sat in his patrol car at a red light just outside a sheriff's station in the city of Palmdale, about 55 miles (90 km) northeast of Los Angeles.

The Los Angeles County sheriff's office on Monday said a person of interest had been detained but provided no details.

The sheriff's office said it would hold its next news conference on the matter at 10:30 am PST on Monday.

Los Angeles County Sheriff Robert Luna at a news conference on Sunday said Clinkunbroomer had been targeted because he was a law enforcement officer.

"Without warning, he was murdered while serving our community," Luna said.

A passerby found Clinkunbroomer at the wheel of his patrol cruiser gravely wounded about 6 p.m. on Saturday and called for help, police said. Clinkunbroomer, who served for eight years on the force, died at the hospital.

Clinkunbroomer, who had just gotten engaged to be married, was a third-generation member of the Los Angeles County Sheriff's office, following in the footsteps of his father and grandfather, the sheriff said.

"Service was running through his veins," the sheriff said in a post on Instagram.

Local, state and federal officials had offered assistance in locating the shooter, Luna said.

This year 83 ambush-style attacks have targeted police in the United States, resulting in 15 officers killed by gunfire, according to the National Fraternal Order of Police.

In a tragic incident that has sent shockwaves through the community, Los Angeles county sheriff's deputy Ryan Clinkunbroome was fatally shot while sitting in his patrol car at a red light on Saturday.

The Los Angeles County sheriff's office made the announcement on Monday, though they did not provide any additional information about the individual. A news conference is scheduled for later today, where officials are expected to reveal more details about the arrest.

The breakthrough in the investigation came after the department released a description of a vehicle believed to be involved in the shooting. Law enforcement received a tip which led them to the person of interest, as reported by the Los Angeles Times. This development provides a glimmer of hope for justice in this heinous crime that took the life of a dedicated officer.

The murder of Deputy Clinkunbroome has rocked the Los Angeles community, leading to an outpouring of support and a reward of $250,000 for any information related to the shooting. The 30-year-old deputy was gunned down as he sat in his patrol car at a red light, just outside a sheriff's station in the city of Palmdale, located approximately 55 miles northeast of Los Angeles.

Speaking at a news conference on Sunday, Los Angeles County Sheriff Robert Luna expressed his outrage over the targeting of law enforcement officers. He stated that Clinkunbroome was intentionally singled out because of his profession, emphasizing that "without warning, he was murdered while serving our community." The sheriff described the incident as a cold-blooded ambush, leaving no doubt that the deputy was a victim of a deliberate attack.

The discovery of Clinkunbroome's gravely wounded body was made by a passerby who promptly called for help. Despite the efforts of medical personnel, the eight-year veteran of the force succumbed to his injuries at the hospital. The loss of Deputy Clinkunbroome, who had recently become engaged, has been deeply felt within the Los Angeles County Sheriff's office. He was a third-generation member of the department, following in the footsteps of his father and grandfather. Sheriff Luna paid tribute to the fallen deputy, stating that "service was running through his veins," in a heartfelt post on Instagram.

The murder of Deputy Clinkunbroome highlights the ongoing dangers faced by law enforcement officers across the United States. ..... In response to this alarming trend, local, state, and federal officials have offered their support and assistance in locating the shooter responsible for this tragic incident.

As the investigation continues, the community remains hopeful that justice will be served. The apprehension of a person of interest provides a glimmer of hope, although the motive behind the ambush and details surrounding the suspect remain unknown. Los Angeles County residents anxiously await the upcoming news conference, where they hope to find answers and closure for the loss of a dedicated and courageous officer.

Los Angeles Sheriff's Deputy Ryan Clinkunbroomer was tragically shot and killed over the weekend in an ambush-style attack. On Monday, authorities announced that a suspect, identified as 29-year-old Kevin Salazar, had been arrested in connection with the shooting. The arrest came after community members provided information that led homicide detectives to identify the suspect and the vehicle used in the crime. Acting on this information, the sheriff's department's Special Enforcement Bureau tactical team went to a home in Palmdale where the suspect was believed to be hiding. While family members came out of the residence, Salazar barricaded himself inside for several hours. Law enforcement officers attempted to de-escalate the situation and peacefully coax the suspect out, but eventually deployed chemical agents, leading Salazar to surrender. Sheriff Robert Luna expressed his pride in the department's handling of the situation, noting that they gave the suspect every opportunity to surrender peacefully, unlike the way Clinkunbroomer was afforded no chance by the suspect. Salazar was taken into custody, and authorities recovered the vehicle and multiple firearms at the scene.

The arrest and subsequent recovery of evidence came after a reward of $250,000 was announced for information leading to an arrest in the case. Images of a vehicle believed to be involved in the attack, a dark gray Toyota Corolla made between 2006 and 2012, were released to the public. The vehicle was later found, along with the aforementioned firearms. However, authorities stress that the investigation is still ongoing, and they encourage anyone with additional information to come forward to assist in the prosecution of Salazar.

During a news conference, Sheriff Luna became emotional as he described the attack on Deputy Clinkunbroomer. He highlighted the sacrifices that law enforcement officers and their families make daily, with the hope of returning home safely. Luna also read a statement from Clinkunbroomer's family, who described him as a dedicated and hardworking deputy who was proud to serve the Palmdale community. Clinkunbroomer's family requested privacy during this time of mourning.

Surveillance video captured the moments before the shooting, showing a black car pulling up to the left of Clinkunbroomer's patrol vehicle at a red light. While the video does not show the actual shots being fired, it does show the black vehicle driving away as the patrol car comes to a stop. A citizen discovered Deputy Clinkunbroomer slumped over in his cruiser and alerted other deputies inside the Palmdale Sheriff's Station. Clinkunbroomer was initially taken to the hospital in his cruiser but was transferred to an ambulance en route. Another deputy took the cruiser to a medical center in Lancaster.

The motive for the shooting remains unclear, and the investigation is ongoing. Clinkunbroomer, an eight-year veteran of the Los Angeles County Sheriff's Department, was described as an exemplary officer who served the Palmdale and Antelope Valley communities with distinction. His father and grandfather had also worked for the sheriff's department, making him part of three generations of law enforcement officers.

This tragic incident has brought attention to the ongoing tensions between law enforcement and the community in Palmdale. In 2015, a settlement involving police reforms was announced in Palmdale and the nearby city of Lancaster following an investigation that uncovered patterns of excessive force and biased policing practices. Monitors overseeing the settlement have noted a lack of progress in recent years, but have also recognized signs of commitment to reforms.

A "person of interest" in the fatal shooting of a Los Angeles County Sheriff's deputy was taken into custody, authorities said Monday.

Sheriff Robert Luna was scheduled to meet with reporters at 10:30 a.m. PDT (1:30 p.m. ET) to reveal more details of a possible break in the case of Deputy Ryan Clinkunbroomer's slaying on Saturday.

A bystander called 911 after spotting the 30-year-old deputy unconscious in his car at 6 p.m. Saturday in the Southern California suburb of Palmdale, officials said.

Clinkunbroomer was rushed to the hospital but could not be revived.

Investigators said Sunday they were looking for a car - a dark-colored 2006 to 2012 Toyota Corolla - that was seen near Clinkunbroomer's vehicle just before the shooting.

Clinkunbroomer had just left the station when he was discovered near the intersection of Sierra Highway and Avenue Q, which is about 60 miles north of downtown Los Angeles, officials said.

Law enforcement officials familiar with the investigation said Sunday that a video clip that shows a car pulling alongside the patrol car before it speeds away is a focus in the investigation.

Clinkunbroomer was a well regarded deputy and had been working as a field training officer for the past 1 1/2 years, officials said.

The victim, a third-generation deputy, got engaged to his girlfriend four days before the fatal attack, Luna said.

Los Angeles County Sheriff's Department Deputy Ryan Clinkunbroomer was killed in an ambush shooting outside the Palmdale sheriff's station on Saturday. An unidentified person of interest in the homicide case has been detained, the department confirmed at about 6:15 a.m. Monday. A department news conference is scheduled for 10:30 a.m.

The sheriff's department said Deputy Clinkunbroomer had just left the Palmdale station and was sitting at a red light at the intersection of Sierra Highway and Avenue Q at about 6 p.m. Saturday when he was found slumped over the wheel of his patrol vehicle by a good Samaritan.

"He was in uniform, sitting in a black and white vehicle marked L.A. County Sheriff's, waiting for a red light," Sheriff Robert Luna said. "Our deputy never even had a chance."

The victim was identified as Deputy Ryan Clinkunbroomer, who was rushed to Antelope Valley Medical Center, where he succumbed to his injuries. He was 30 years old.

There was no information provided on the shooter or a possible motive.

I want to let to our community know Deputy Clinkunbroomer left his family tonight to serve our community. He laid everything on the line to serve us. He wore a uniform just like other @LASDHQ deputies wear, driving in a police car, and he was senselessly murdered tonight. pic.twitter.com/Jqc2sSB63c

"We're gonna catch the person who did this," the sheriff said during a press conference late Saturday evening. "Every resource that the Los Angeles County Sheriff's Department has to bear is going after you."

Investigators are analyzing a video that shows a sedan slowly pulling up behind an LASD vehicle at around the time that the shooting occurred before speeding away, Luna said.

During a press conference on Sunday, the sheriff said that the vehicle of interest is a dark gray 2006-2012 Toyota Corolla.

"We really need your help. We need to get this guy off the street," Luna said. "He ambushed and killed - murdered - one of our deputies. We need your help to get him off the street."

The sheriff further noted that Clinkunbroomer had spent about eight years with the department and transferred to the Palmdale station in July 2018. He had been acting as a field training officer for nearly two years, Luna said.

"Not just anybody becomes a field training officer," Luna said. "It's usually the best of the best."

Clinkunbroomer was a third generation LASD member, behind his father and grandfather.

"Service was in his blood," the sheriff said.

He had just become engaged to his girlfriend four days ago, the sheriff said. Clinkunbroomer leaves behind his fiancee, parents and grandparents.

"He didn't deserve this," an emotional Luna said. "This is so unfair. We're hurting because we lost somebody. It hurts bad. It sucks, just to put it bluntly. Our hearts absolutely go out to his family."

Sheriff Luna withheld specifics on the investigation as it remains in its early stages. He says that as new information comes to light, the public will be alerted.

During a procession early Sunday morning, hundreds of law enforcement officers escorted Clinkunbroomer's body to the Los Angeles County Coroner's Office.

A large area on the street outside of the station was surrounded by crime scene tape. An LASD vehicle was also taped off outside of the hospital where the deputy was taken after being discovered in the patrol car.

"Somebody saw something. Somebody knows something," Luna said. "There is a family here at this hospital grieving an unimaginable loss. We need your help."

Politicians, law enforcement officials and community leaders took to to social media to offer their condolences over the tragic loss of life throughout the day on Sunday, and flags at the state Capitol and Capitol Annex Swing Space were flown at half-staff.

During Sunday's press conference, County Supervisor Kathryn Barger said she would seek $100,000 toward a reward to locate the suspect or suspect involved, which the Palmdale Mayor Laura Bettencourt said the city would match. Richard Pippin, the President of the Association for Los Angeles Deputy Sheriffs, has also pledged an additional $50,000.

Clinkunbroomer was honored outside of the Palmdale sheriff's station Sunday evening at 7 p.m. with a candlelight vigil.

Anyone with information or who may have witnessed the incident is urged to contact homicide investigators at (323) 890-5500.
