Three Nevada men have been questioned by investigators about vandalism in an environmentally fragile area of Death Valley National Park that may have killed one of the rarest fishes on earth, officials said Friday.
No arrests have been made in the April 30 intrusion while authorities continue to investigate what could be a federal crime, Nye County Sheriff's Sgt. David Boruchowitz said. He said evidence includes DNA and video recordings.

Investigators determined the three had been shooting rabbits in the area before they climbed a fence into Devils Hole, a protected sanctuary in Nevada just east of Death Valley National Park in California, Boruchowitz said.
(...) The National Park Service said they left beer cans and vomit, and one man waded into Devils Hole, leaving his boxer shorts in the water.

The Park Service offered a $5,000 reward for the arrest and conviction of the intruders, and the Center for Biological Diversity added another $10,000
