Excerpts from the herald news.com:

Troy FPD Lt. John Probst was preparing to return from a vacation with his girlfriend when he collapsed Tuesday morning, Troy Fire Protection District Chief Andy Doyle said. Probst was taken to a hospital, but did not survive.

“It was some kind of medical issue, but we weren’t told more than that,” Doyle said Wednesday morning. “Everybody here is in shock. It’s hard to believe.”

Doyle said the Estero, FL fire chief notified Troy firefighters of Probst’s death Tuesday afternoon.

Probst, 35, began his career with the Hometown Fire Department in 1999 and came to Troy in 2006. His last assignment was supervising a shift of four firefighters at Fire Station 1. Probst and his crew received a lifesaving award two years ago for resuscitating a man who’d gone into full cardiac arrest.

Probst was also a member of the agency’s Hazardous Materials and Technical Rescue teams who loved training.

“He was a really good fireman. If you needed something done at a scene, you knew John could get it done or help someone get it done,” Doyle said.

Probst is survived by a 14-year-old son, his parents, two brothers, and two sisters. Funeral arrangements were pending Wednesday.
