Four police officers in Florida have died in the line of duty so far this year, bringing the national total of law enforcement officer fatalities to 67 for the first six months of 2014.


In Florida, two were struck and killed during traffic stops, while two others were shot in altercations with suspects.


Craig Floyd, Chairman of the National Law Enforcement Officers Fund, says it's a troubling trend across the country, resulting in an increase of 31 percent in the number of police officer deaths, according to preliminary data.


Gun-related deaths alone are up 56 percent from last year, with 25 officers killed by firearms incidents between January 1st and June 30th.


Traffic-related fatalities are the second leading cause of death among law enforcement officers, increasing 37 percent so far this year, with 26 fatalities, compared to 19 deaths last year during the first six months of the year.
