LAS VEGAS, Nevada: National Park Service officials have said that a fifth set of human remains were found in Lake Mead near Las Vegas.
The remains were discovered as water levels recede at record rates.
The discovery is the second time this month that remains have been found in the largest reservoir in the U.S., which was formed by the Hoover Dam on the Colorado River, and supplies drinking water to millions of people in California, Arizona, Nevada and parts of New Mexico.
According to the park service, the remains were discovered at Swim Beach in the Lake Mead National Recreation Area this week.
The Clark County Medical Examiner is working to identify the remains and discover the cause of death, the park service said.
Late last week, the Las Vegas Metropolitan Police Department said a gun was also found by a journalist and recovered in "close proximity" to the remains most recently discovered.
In a statement, the department said, "Although it is not uncommon for firearms to be found at the lake, it is too early to determine whether it is connected to the current investigation."
