Since the start of 2018, at least 37 law enforcement officers across the U.S. have died while on duty -- with 24 of the deaths caused by gunfire.
Roughly 135 cops died in 2016, making it the deadliest year for police officers in at least five years, Fox News has found. While there were fewer deaths in 2017, the numbers weren’t much better: A total of 129 officers died last year. And 46 of those were caused by gunfire.
Read on for a look at officers who have died in the line of duty so far this year.
Officer Amy Caprio
While responding to a suspicious vehicle call on May 21, Police Officer Amy Caprio with the Baltimore County Police Department was “critically injured,” authorities said.
The officer, who served with the department for nearly four years, was taken to a nearby hospital but was pronounced dead.
After a manhunt that ended the following day, four teenagers were arrested in connection to her death.
One of the teens -- Dawnta Anthony Harris from Baltimore -- allegedly “drove at” the officer after she told him to get out of his vehicle as the three other teens, who have not yet been identified, burglarized a house.
According to police, Harris has been charged as an adult with first-degree murder and is being held at the Baltimore County Department of Corrections.
Caprio is the first female police officer to die in the line of duty in the Baltimore County Police Department’s 148-year history, officials told Fox News.
Deputy William Gentry
Florida Deputy William Gentry died on May 7, a day after being shot in the head while responding to a dispute between neighbors over a cat that had been shot, police said.
After speaking with the cat's owner, the Highlands County officer approached the man suspected of shooting the cat, Joseph Edward Ables, 69, at his Lake Placid front door. Sheriff Paul Blackman said Ables then shot Gentry in the head shortly before 8 p.m. on May 6. The deputy was airlifted to a Fort Myers hospital.
The sheriff's office statement said Ables was a convicted felon with a history of violence toward law enforcement.
Gentry, 40, was a field training officer and served for over nine years with the Highlands County Sheriff's Office, where his brother is a detective, Blackman said.
"This is an unimaginable tragedy for our agency," the sheriff added.

Officer Tamby Yagan
Patterson, New Jersey police Officer Tamby Yagan crashed into a parked car on April 22 while on duty, killing the 41-year-old.
The cause of the accident, including if Yagan suffered a medical emergency before the crash, is still being investigated, according to NorthJersey.com.
“He was a cop's cop,” Police Director Jerry Speziale told the newspaper. “He's somebody who went above and beyond. He was a true community person.”
“He would give you the shirt off his back,” Struyk said. “You could call him any time of night and he would be there for you.”
Yagan was a member of the Patterson police force since 2005. Prior to that, he was a volunteer firefighter. He leaves behind a young son, according to local reports.

Officer Greggory Casillas
Pomona, California police Officer Greggory Casillas, 30, was fatally shot March 9 after he and another officer chased a suspect who "barricaded himself in a bedroom" and "began firing through the door" as officers tried to contact him, Capt. Christopher Bergner of the Los Angeles County Sheriff's Department told reporters. A second officer was injured, authorities said.
The confrontation led to a 15-hour standoff with authorities and ended with the suspect's arrest March 10, Los Angeles County Sheriff Jim McDonnell said.
"For the last 15 hours, we attempted to make an arrest of this individual and just did so successfully minutes ago," McDonnell said during a news conference.
The situation began when Pomona officers received a report of a "person driving recklessly," the Los Angeles County Sheriff's Department said in a statement. The suspect ultimately led police on a chase before crashing and fleeing on foot. The suspect then "ran into an apartment complex and the officers gave chase," Capt. Christopher Bergner of the Los Angeles County Sheriff's Department said.
Dispatchers received a call of an "officer down," at around 9:10 p.m. local time. Pomona police Chief Mike Olivieri said in a tweet that one officer had died and the other was in stable condition.
"It is with a heavy heart that I must report that one officer did not survive," the tweet said.
Officer Ryan Morton
Clinton, Missouri police Officer Ryan Morton was fatally shot and two other officers were injured as they responded to a 911 call at a home in Missouri.
The alleged shooter, later identified as James Waters, opened fire from inside the house when officers tried to apprehend the individual. The suspect was found dead inside the home.
Since news of Morton's death broke, authorities announced that Morton and the other officers were sent to the wrong house -- about 15 miles away from where they were supposed to be.
"The 911 call that came in was somehow attached to that [Clinton] address," Missouri Highway Patrol Sgt. Bill Lowe said, according to the Kansas City Star.
Lowe said it was a "coincidence" the officers were directed to that address.
"It is tragic that happened. But the fact is they were in the act of committing crimes within that house," Lowe said. "When (the officers) entered that house, they were doing what they needed to ensure no one was hurt and there wasn't any other problems."
Lowe said the loss would greatly impact the "small department."
“It’s a small department. It’s small enough that you know each individual officer and the community knows each individual officer, and it’s hard to put into words when you’re talking about an agency of this size, a community of this size where something tragic like this happened just seven months ago,” he said.
Morton, a 30-year-old Army veteran, was with the Clinton Police Department from February 2015 through January 2017, the St. Louis Post-Dispatch reports. He decided to return to the force after fellow officer Gary Michael was fatally shot at a traffic stop in August 2017.

“Deputy Locklear was loved, honored and respected,” Kersey said in a Facebook post. “He brought great joy and pleasure in our hearts and spirits in our time of having him as a brother in this family we like to call home, here at the Scotland County Sheriff’s Office.”
His patrol car number 143 will be retired, according to WBTW-TV.

"Deputy Jacob Pickett made the ultimate sacrifice for his community this morning," Sgt. John Perrine, a public information officer for the Indiana State Police, tweeted. "Rest easy sir."
Pickett, an Indiana native, had been in law enforcement for nearly eight years. He had been working as a K-9 handler, patrolling the streets with his loyal partner "Brick," for the Boone County Sheriff's Office for the past two years.
He's the first person killed in the line of duty from the department since 1935, police said.

Officer Justin Billa
Alabama Police Officer Justin Billa was fatally shot on Feb. 20 as he and other law enforcement officials responded to a woman’s murder.
After finding the slain woman, police identified her ex-husband, Robert Hollie, as a “person of interest.” Billa and other officers with the Mobile Police Department established a perimeter around Hollie’s house and asked him to come out, but he opened fire instead, Mobile Police Chief Lawrence Battiste said.
Billa was shot and later died at a hospital, according to Battiste. Hollie was also killed in the shooting, though it’s unclear if he shot himself or was struck by officers.
Billa, who was named “Officer of the Month” in June 2016, had only been on the force for two years. When he was given the award, his commanding officer praised his attention to detail and professionalism.
“We need to go back to helping people instead of just taking them to jail and creating bigger problems,” Billa told WALA-TV in July 2016. “That’s my idea of good policing, and I feel like that’s what the chief is working towards.”
Billa also said he spent time with his wife before he left for work every day.
"She tells me she loves me every day before I leave for work. And I make sure I do the same," he added.
Aside from his wife, Billa also left behind a young son.
