A veteran City of Marietta firefighter died Thursday after collapsing at the scene of a wreck.

Lonnie Lee Nutt, 49, a firefighter engineer, appeared to have suffered a medical emergency, the Marietta fire department said late Thursday.

Around 4:30 p.m., Nutt drove Engine 53 with two others on board to a wreck with injuries on Whitlock Avenue, less than a mile from Station 3, the fire department said in a statement late Thursday night.

“When they arrived on the scene and begin to assist with the injured patient, Fire Engineer Nutt fell to the ground with a medical issue of his own,” the fire department said.

Firefighters rendered aid to Nutt until an ambulance arrived.

“He fell from what appeared to be a massive heart attack, and they immediately started working him as well as trying to help the patient that was already there,” Scott Tucker, the city’s fire marshal, told WSB radio.

Nutt was transported to WellStar Kennestone Hospital, but could not be revived, Tucker said.

Nutt began his career with the city in May 1994 and had served as a fire fighter, inspector, investigator and most recently as a firefighter engineer.

“We had a lot that we depended on him for because he was a very good firefighter,” Tucker said. “He was somebody that was knowledgeable. You could depend on him and he had the expertise to do a lot of things.”

An Oklahoma native, Nutt lived in Kennesaw with his wife, Tucker said. He is also survived by a daughter.
