Crews are searching a North Texas lake for a missing man and his grandson after their fishing boat was found empty.
Capt. Gary Dugan of the Texas Parks and Wildlife Department said lifejackets were found on board the boat, still wrapped in plastic. He speculates that one person may have fallen into the water and the other may have jumped in after him.
Dugan said Tuesday night that the water temperature was around 55 to 60 degrees.
