KENOSHA -- A grass fire reported at a park in Kenosha led to the discovery of a body early Wednesday morning.

"It is a current death investigation," Kenosha Police Lt. David Molinaro said.

Molinaro said the fire was reported around 12:42 a.m. When the fire was extinguished, authorities found a burned body. They believe it is an adult male.

On Wednesday morning, crime tape blocked most of the northern entrance to Simmons Island Park near 45th St. and Kennedy Dr.

"Every unfortunate death we come across we consider a death investigation until we rule it differently," Molinaro said. "We don't know if it's a homicide or suicide."

Neighbors in the area said they were stunned.

"I'm a little nervous," said Tony Franich, who lives across the street. "We've never had anything like this happen here before."

Rebecca Stevens' backyard overlooks Simmons Island Park. She said she was awakened by noise and police cars around 1:30 a.m. Wednesday.

"I knew it had to be something big because the whole area was lined with squad cars," Stevens said.

She said she's always considered the park safe.

"We're always out here walking," she said. "It's a great area. This is a shock."

Police do not believe there is a danger to the public.
