FL, OH- Investigators say a propane leak was the likely cause of an explosion and fire that injured four people at a Henry County home.

Fire crews were called to the home of George and Teresa Maldonado on Henry County Road K in about 10:35 p.m. Thursday.

Shane Cartmill, spokesman for the Ohio State Fire Marshal’s Office, said the house was destroyed. Damage was estimated at $150,000. Two investigators from the office ruled out criminal intent, he said.

“The cause of the explosion and fire remains undetermined at this point, but we have not ruled out the possibility of a propane leak in the basement of the home,” Mr. Cartmill said.

Chief Steve Eberle of the Florida-Flatrock Township Fire Department concurred with the likelihood that a propane leak figured into the blast.

“The cause is expected to be accidental,” he said.

The Maldonados, a 12-year-old boy, and another adult male were in the home at the time, Chief Eberle said, declining to name the other two occupants. Mr. Cartmill said all were injured but were expected to survive.

The two men – one age 39 and the other 36 – were flown to Mercy St. Vincent Medical Center in Toledo. Mrs. Maldonado, 36, and the young boy were treated at Henry County Hospital in Napoleon.

“One was helped out of the house by a neighbor, and the other three were out of the house by that time,” Chief Eberle said.

Firefighters from Holgate, Hamler, and Napoleon assisted the Florida-Flatrock Township department. The chief said the house is at a commercial hog farm.

Florida, about 49 miles southwest of Toledo, is along the Maumee River just east of the Henry-Defiance County line.
