More US police officers die on duty than before : report

More police officers have died in the line of duty this year in the United States than in 2017, according to data released Thursday.

The most common cause of death was gunfire, and vehicular accidents claimed nearly as many officers' lives.

The National Law Enforcement Officers Memorial Fund said in a report that 144 federal, state and local officers have died so far in 2018. That figure represents roughly a 12 percent increase from the 129 who died in 2017.

The majority of the officers who died were either shot 52 this year, up from 46 in 2017 or fatally injured in car or motorcycle crashes, which accounted for 50 deaths.

Other fatalities involved heart attacks, strokes, drownings and cancer and other illnesses among those who responded to the 9/11 World Trade Center attack.

Of the officers who were shot, eight were killed during investigative activity and six were killed while responding to calls of a domestic or public disturbance, according to the report.

Two were fatally shot while serving warrants, two died while handling or transporting prisoners and two others were inadvertently shot by other officers.

Craig Floyd, the fund's chief executive officer, called the increase in deaths disappointing after a decline in 2017.

"Sadly this reminds us that public safety is a dangerous job and can come at a very steep price," Floyd said in a statement accompanying the report.

"We must never take the service and sacrifice of law enforcement officers for granted, and we must remember the families of the fallen who are left behind."
