It was created in 1962 when Congress enacted a joint resolution declaring May 15 as National Peace Officers Memorial Day to honor law enforcement officers killed or disabled in the line of duty.
The resolution also created National Police Officers Week.
According to statistics reported to the FBI, 106 law enforcement officers were killed in the line of duty in 2018, including Cpl. Eugene Cole of the Somerset County Sheriff's Office.
Cpl. Cole's name and the names of all the other fallen officers will be formally added to the National Law Enforcement Officers Memorial in Washington, D.C. during a candlelight vigil on Monday night.
