LAS VEGAS (AP) — The body found inside a barrel on the newly exposed bottom of Lake Mead after the lake's level was depleted amid drought is that of a man who was shot, police said Tuesday.

The killing probably happened between the mid-1970s and the early 1980s because the victim was wearing shoes that were manufactured during that period, said homicide Lt. Ray Spencer, the Las Vegas Review-Journal reported.

The barrel was found Sunday in the Lake Mead National Recreational Area by boaters who informed authorities.
