This is the fourth time human remains have been found at Lake Mead National Recreation Area since May.
In the latest incident, park rangers got a call Saturday morning about skeletal remains at Swim Beach area, National Park Service officials said in a statement.
Rangers set up a perimeter at the beach to recover the remains with help from divers from the Las Vegas Metropolitan Police Department, according to the Park Service. A coroner was also called to determine the cause of death.
At least three different sets have previously been found at the lake, where water levels have plunged to unprecedented lows amid an unrelenting water crisis in the West.
The previous remains discovered, including a body that was found in a corroding barrel with a gunshot wound, were in advanced stages of decomposition and thus difficult to extract DNA from, officials said.
It’s unclear how long the latest remains found have been in the lake. The homicide division of Las Vegas Metropolitan Police is not currently handling the investigation, Lt. Jason Johansson told CNN.
