EPHRAIM, Wis. (AP) -

Officials say there were no survivors when a small plane crashed in a state park in northeastern Wisconsin.

Authorities did not say how many people were on board the private plane when it crashed in Door County Sunday night or if anyone on the ground was injured.

Sheriff's officials say the plane was found in the woods of Peninsula State Park, a popular camping spot. The sheriff's department got a call about 8:30 p.m. about a crash that was heard after a plane circled near Ephraim.

At least a-half dozen agencies searched by land and in the waters of Green Bay for about an hour before the plane was found in the park.
