The Seminole County sheriff's office is investigating the incident.
No arrests have been made. The name of the other firefighter was not released.
Nadeau said Patterson joined the fire department six years ago after he finished a career as a narcotics agent in New Mexico. He described him as a good leader with a strong spirit. Through his six years at the department, he made his way up to captain and firehouse chaplain.
“He would give the shirt off his back in a blizzard,” Nadeau said.
He said the station is grouping together and working to support the other firefighter.
“We are here to support the family and the other firefighter,” Nadeau said. “Whatever the outcome may be, we'll be there for him.”
