The Massachusetts Turnpike reopened early Thursday morning following the discovery of a body on the roadway.

Massachusetts State Police were called to the westbound side of the Mass. Pike near Exit 10 in Auburn around 10 p.m. Wednesday. Two lanes of the turnpike were closed for hours as detectives investigated the death and awaited the arrival of the medical examiner to remove the body.

The body of a person who suffered "serious injuries" was found. Police are working to determine the person's identity and how the body came to lay in the heavily traveled roadway.

"There is no overpass nearby. Troopers have not located any unattended vehicles in the area and there were no prior reports of pedestrians on the highway," Massachusetts State Police spokesman David Procopio said.
