BONITA SPRINGS, Fla.- The investigation continues Monday into why a Bonita Springs house burst into flames over the weekend.

Caution tape still surrounds the house on Harold Street and it's easy to see why the fire department is calling it a total loss. It appears flames devoured the walls.

Paul Navarro, his wife and two children, live right down the road from the burned out home.
They say they noticed suspicious activity took place at the house, with people coming and going all hours of the night.

"My neighbor said it was a meth house, I'm pretty sure," said Navarro.

They worried so much about their neighbors they encouraged their children play in the backyard, not in the front yard.

"It smelled kind of funny in that house, like weird odor like, that drug smell," he explained.

They say it's especially disturbing because the house is feet from Bonita Springs Elementary School.

Flames devoured the house early Sunday morning. Nighbor Cris Stevens shot this cell phone video as it went up in smoke. He says, even after the fire, people continue to come and go.

"We've had maybe half a dozen or ten or so come, drive by slowly look at it, turn around and leave," he said.

"We knew something was going to happen over there, I feared someone was going to get murdered," said another neighbor who did not want to be identified.  She also fears for her safety

"One time somebody came to the door and he stuck a rifle or shotgun out the door, I was sitting right there and it was pointed right at me," she said.

The owner of the home could not be reached for comment.

The investigation continues.
