A Los Angeles County sheriff's sergeant was shot and killed Wednesday afternoon while responding to a home burglary call near Antelope Valley College in Lancaster.
Los Angeles County Sheriff's Department Sgt. Steve Owen, 53, died shortly after the incident, Executive Officer Neal Tyler said at a press conference.
The suspect in the shooting — an armed burglar — was arrested after a chase.
"This has been a very dark day for the L.A. County Sheriff's Department," Capt. Steven Katz said. "We're all suffering right now. His family certainly is suffering, his law enforcement family is suffering. It doesn't get worse than this, folks."

What happened
The incident took place near the 3200 block of West Avenue J7 near Antelope Valley College shortly after noon. Owen responded to the burglary call, Katz said, along with a deputy sheriff.
Owen was shot immediately after he arrived at the location, officials said. The suspect fled and tried to commandeer Owen's cruiser, putting the car in reverse and ramming it into another deputy's car. That is when the other deputy at the scene shot the suspect in the upper torso.
The suspect fled on foot and hid in at least one house, where it is believed that he took hostages, Katz said. Two teenagers — one male and one female — were hiding in the house and texted police, telling them that the suspect was there.
Authorities believed that the teens were in danger, Capt. Jack Ewell said at the press conference. The suspect fled, climbing a wall before he was taken into custody.
The deputy and sergeant were transported to a local hospital for treatment, as was the suspect.
Antelope Valley College tweeted that it had been placed on lockdown shortly after the shooting took place. That lockdown was later lifted.
Sgt. Owen's story
Owen was a 29-year veteran of the department, Tyler said, and a recipient of the medal of valor. He had been a sergeant at the Lancaster station for five years, where he worked first as a deputy before he was promoted to sergeant five years ago.
"Steve clearly is very much a hero. Not that he wasn't before this happened," Tyler said.
Officials were able to locate Owen's wife, a sheriff's arson explosives detective, and get her to the hospital before her husband succumbed to his injuries, Tyler said. His mother and his adult children — a son and daughter — were also there before he died.
Owen received his medal for his response to a suspect who was holding a hostage, according to a Sheriff's Department newsletter. The suspect was wearing a bulletproof vest, pointing a gun at the victim's chest and head area, which made a clean shot impossible, according to the newsletter.
Owen requested assistance from the department's Special Enforcement Bureau, but realized he didn't have time to wait for them to respond, according to the newsletter. He directed a deputy to open a passenger window, and that deputy deployed his Taser and hit the suspect in the right arm, allowing the hostage to escape.
Owen saw the suspect clenching a handgun, according to the newsletter, fearing he continued to pose a threat. He directed another sergeant to use a Taser again, incapacitating the suspect and allowing another deputy to take the suspect's gun before subduing the suspect.
"Sgt. Owen was an outstanding law enforcement professional who I had the opportunity to know and work with," Supervisor Mike Antonovich said in a statement. "He was senselessly murdered while responding to a call for help. His loss leaves a significant void for all those who knew him."

The suspect, who has not yet been named, had prior convictions. A weapon was recovered, Katz said. Deputies don't believe there are any other suspects.
Tyler said that he called Sheriff Jim McDonnell, who had been attending a conference on human trafficking. McDonnell had planned to spend several more days on vacation, but upon hearing of the incident, McDonnell said that he would catch the first plane back, so he is expected back either Wednesday or Thursday.
The last time a Los Angeles sheriff's deputy was killed on duty was in 2005, according to the Officer Down Memorial Page.
