Grapevine police are investigating after a body was found Wednesday morning in a wooded area near Grapevine Lake.[[393413931,C]]

Officers responded at about 6:30 a.m. to the 1000 block of Oak Grove Loop South, where they made the gruesome discovery. Police said the person had been partially dismembered and burned.

Police aren't saying if the person is a man or woman, but they confirm it's an adult.

"The body appears to have been set on fire, and the body has some degree of dismemberment," said Grapevine Police Sgt. Robert Eberling.

Police say they're still questioning one witness who may have been the first to notice the body.

Police wouldn't confirm how officers were alerted to the fact that a body was in the woods, and at this point officers don't know how long the body was in the woods.

The Texas Rangers and an Evidence Recovery Team from the FBI are helping with the homicide investigation. This would be Grapevine's first homicide in three years.

"There are some scattered trails throughout that area of the park," Eberling said. "But I know it wasn't in close proximity to a paved walking trail."

The 2016 Grapefest Festival begins Saturday along Main Street, about one-and-a-half miles away from Oak Grove Park.

Police say there's no reason for festival-goers along Main Street to feel unsafe.
