FREEMANSBURG, Pa — Mourners paid tribute Tuesday to a police officer killed in the line of duty last week as a motorcade escorted the coffin through the small Pennsylvania town he served and funeral services drew 1,000 law enforcement officials from at least three states.

Private and public services were held for Freemansburg police Officer Robert Lasso, who was remembered as a great cop and devoted father.

“Protect and serve — those are not just words, they really represent the life of Robert Lasso,” the Rev. Richard Teitsworth said at Northampton County Community College, where some 2,000 people attended a public memorial. “The law enforcement fraternity honors one of their own who gave the supreme sacrifice.”

Added Lasso’s police chief, George Bruneio: “Those who knew Robert know how much we lost.”

Among the mourners were the mayors of Allentown, Bethlehem and Easton; Lt. Gov. Jim Cawley; and officers from several police departments and from New Jersey and New York.

Lasso, 31, who had been on the force nine years, was shot in the head while investigating a report of a domestic disturbance. George Hitcho Jr., 46, allegedly fired on the officer after Lasso pointed a stun gun at his dogs.

Lasso had ended up at the back of Hitcho’s house, authorities said, where Bruneio instructed the officer to “shoot the dogs.” That’s when Hitcho pulled out a shotgun and fired, authorities said.

Hitcho has been charged with homicide and is in the Northampton County Prison.
