LITTLE ELM — An 18-year veteran of the Little Elm Police Department was killed in the line of duty Tuesday afternoon after responding to a report of an armed individual in a Little Elm neighborhood. Detective Jerry Walker, 48, was among the first Little Elm officers who responded to the call.

He is survived by four children, the youngest a few months old and the oldest 22. Detective Walker is the first Little Elm officer killed in the line of duty.

Shortly after arriving on the scene, officers established a perimeter to contain the situation when they were met with gunfire from inside the home. Police returned fire. It was at this initial exchange that Detective Walker was wounded. He was transported to Denton Regional Health Center where he died, despite the efforts of the medical staff.

As of Tuesday evening, the area immediately adjacent to the site of the shooting is still an active crime scene with officers of the Denton County Sheriff’s Office and the Frisco Police Department assisting Little Elm officers.

The unidentified suspect remains in the home and is believed to be alone. Earlier that evening, a team of officers safely extracted an elderly female relative of the suspect through a window. No other injuries have been reported in connection with this incident.

“It is with a heavy heart and sadness that we announce the passing of Detective Jerry Walker,” said Police Chief Rodney Harrison during a news conference this evening. “He was a model officer and a person who will be missed here at the department and in the town.”

An update briefing has been scheduled for 2 p.m. Wednesday in the Emergency Operations Center, 88 West Eldorado Parkway, within the Public Safety Building. Services for Detective Walker are pending.
