Authorities are searching for two boaters missing since Monday.

Officials at Grand River Dam Authority said at 8 p.m. Monday, a fisherman notified lake patrol of a capsized boat in the river below Pensacola Dam.

An investigation by the GRDA revealed the boat likely contained two men - Alan Lee Long, 47, of Anderson, Mo., and Ricky Beason, 20, of Noel, Mo.

Several lake patrol boats and the GRDA helicopter, utilizing its forward looking infrared camera, searched the area Monday evening until severe weather and lightning strikes forced them to evacuate the effort.

The search continued Tuesday morning.
