(CNN) — The number of law enforcement officers shot to death in the line of duty is up by more than 50% this year, and the leading method of those shootings was ambush-style attack.
That’s according to the nonprofit Washington-based National Law Enforcement Officers Memorial Fund, which released its findings Tuesday.
There were 50 officers killed by firearm in 2014, up from 32 the previous year. Of those 50 officers, 15 were killed in ambush attacks, the Memorial Fund said.
Ten were killed ambush-style in 2013, the Fund said.
The FBI, however, found that five officers were ambushed and killed in 2013.
According to the Fund’s 2014 report, 126 federal, state, local, tribal and territorial officers were killed in the line of duty in 2014, compared to 123 in 2012 and 102 in 2013.
