Lawrence police officers investigate a fatality accident Saturday at Riverfront Park. Police say one person died when a Jeep overturned early Saturday near the park entrance.

One person died after they were thrown out of a vehicle they were driving in Riverfront Park early Saturday, Aug. 27, 2011.

One person is dead after a vehicle overturned near the entrance to Riverfront Park in North Lawrence, said Lawrence Police Sgt. Mike Monroe.

Early Saturday morning, at the entrance to Riverfront Park at North 1800 Road, police were investigating the one-vehicle incident that was called in by a passerby about 6 a.m. The vehicle, a yellow Jeep Wrangler, could be seen several hundred yards past the levee between the fork in the road, just past the railroad tracks. The body was several feet outside of the Jeep, and the vehicle was heavily damaged.

Tire marks indicated that the vehicle drove between the two lanes of gravel road, going over the levee and slightly past some large rocks dotting the trail of the park.

Monroe said that it’s unclear what time the accident occurred, but placed the time frame between midnight and 6 a.m., when it was called in. An accident reconstruction team was on scene trying to determine the dynamics of the incident, Monroe said.

As of 2:45 p.m. Saturday, Lawrence Police Sgt. Ted Bordman said the investigation was ongoing, and he was not able to release any other information about the accident or the gender or age of the deceased.

Bordman said police would probably issue a news release with more details, but he did not say when that would be available.
