The search is set to resume for two Illinois men who went missing at a southern Wisconsin lake after the bodies of two of their friends were pulled from the water.

Authorities in East Troy say the four were staying at a house on Lake Beulah. Wisconsin Department of Natural Resources warden Jason Roberts says the four ranged in age from 20 to 23 years. Their hometowns haven't been released.

Friends told investigators the four went outside to smoke about 2:30 a.m. Sunday and didn't return before the others went to bed. The friends discovered them missing when they awoke about 9 a.m. They found footprints in the snow to the boathouse and a canoe overturned in the lake.

Two bodies were recovered from the lake Sunday evening. The search will resume Monday.
