PROSPECT, Conn, (WTNH) — State police are calling the death of the Southern Connecticut Pop Warner football president “suspicious.”

Investigators were called to Paul McGrath’s home in Prospect Monday after a neighbor found him unresponsive.

Rich Photos, the president of Pop Warner New England Region, said that McGrath had just moved to the new neighborhood in Prospect only six months ago.

State police said the injuries sustained by McGrath, 54, were “suspicious” in nature. Detectives from the Central District Major Crime Squad are now leading the investigation.

The office of the chief medical examiner said an autopsy was conducted, but the cause and manner of death are pending further studies.

In a Facebook post Monday night, Southern Connecticut Pop Warner (SCPW) announced the passing of McGrath.

“There are no words to express the shock and disbelief that we are all experiencing as this was so sudden… Paul’s love for his Naugatuck Family and SCPW will truly be missed,” the post said in part.

Photos met McGrath 15 years ago through Pop Warner. They developed a close bond despite leading rival football programs.

“We were almost like brothers. We were rivals as well. We were both two small town football programs, we always played each other,” Photos said.

McGrath was in his 22nd year of volunteering with Southern Connecticut Pop Warner. He became president in January.

“To want to run a league and deal with all the things that come along with it, in your spare time without having any kids, I think that says a lot about a person and where your passion is,” said Phil Bryant, vice president of Central Connecticut Pop Warner.

McGrath was talking to Bryant last week about scheduling a trip for nationals this year, and Bryant said nothing seemed out of the ordinary.

Bryant said McGrath’s passion and energy was always very apparent and he is going to miss his close friend.

“You can’t replace a Paul McGrath, you can just hope another one comes along,” Bryant said.

State police said there does not appear to be a threat to the public.
