Valrico, Florida -- Firefighters putting out a burning mobile home overnight found a body inside and took a man carrying a hammer into custody nearby.
The fire started shortly before 1 a.m. Monday at Oakhill Village Mobile Home Park in Valrico, along State Road 60 just east of Miller Road.
Hours before the mobile home next door burned to a charred shell, Nancy Ball saw a strange man pacing nearby, holding something.
"I thought, 'What's he got in his hand?' And I looked, and it looked like a hammer," Ball said.
"A while later he comes over and he asks me to take him to the mental hospital. I told him I couldn't do it."
Instead, around midnight, Ball said she called 911.
"He saw me on the phone and then he went back, and a few minutes later he got on his bike and left," she said.
Hillsborough Sheriff's deputies rolled up to the mobile home park planning to find and talk to the man carrying the hammer. But the deputies found something disturbing: a mobile home on fire next door to Ball's home.
"Something caught my eye and I looked over there and I saw a flicker and I thought it was the lights going off and on or something," Ball said. "But it was fire. And it started going fast."
Responding Hillsborough County firefighters said there was already heavy smoke pouring out as the fire tore the building apart.
Once firefighters could safely push into the home, they found Archie Ennis Carr inside, dead.
Deputies caught up with the man they say was carrying the hammer, 42-year-old Frank Stanley Chapman, Jr.
Investigators say Chapman made remarks about setting the mobile home on fire.
After taking the man into custody and questioning him, investigators arrested Chapman with on a count of first-degree arson. He was additionally charged with felony murder Monday evening.
It appears the two men were family members who lived together in the mobile home, investigators said.
Detectives also hope to discover whether Carr was already dead before the fire broke out.
