State police in Illinois have a mystery to solve.
They’re looking for help in trying to find the identity of a man who lost his arm.
Boaters found the arm floating in Lake Mattoon on Sunday evening.
The body part has several distinguishable tattoos, including one of a skeleton holding a Green Bay Packers’ helmet, WAND reported.
The other tattoo appears to be a letter or number.
A dive team searched the lake as part of a death investigation after the arm was found, WCIA reported.
