SHAWANO, Wis. (AP) -- Authorities say they have a person of interest in custody for a death in Shawano County Tuesday.

Sheriff's Capt. Tom Tuma says a 53-year-old Birnamwood man was found dead after the man who was later arrested called deputies about 7:20 a.m. Tuma says the victim's death was due to the "aggressive actions of another", but he declined to be more specific.

Sheriff's officials say the 20-year-old male caller maintained contact with a dispatcher until deputies arrived.
