Second set of human remains found in receding Lake Mead waters

Authorities in Nevada have recovered another set of human remains from Lake Mead as a devastating drought has depleted the massive reservoir outside Las Vegas.

Two sisters paddle boarding in the lake on Saturday spotted the bones, which they initially thought were the remains of a bighorn sheep.

After spotting a jaw bone, they realized the remains were human and contacted park officials. National Park Service rangers collected them from Callville Bay, part of an area that is popular for boating and other water recreation.

The discovery came a week after dwindling lake levels unearthed a barrel containing the body of a man who authorities said had been shot decades ago. Police estimate the man was probably killed between the mid-1970s and the early 1980s because he was wearing shoes made in that period.
