GEORGETOWN, Calif. — One man died and another was injured in a mountain lion attack in a remote area in Northern California on Saturday, according to authorities.

An 18-year-old man called authorities around 1:13 p.m. to report that he and his 21-year-old brother were attacked by a mountain lion while antler shed hunting in the Georgetown area, according to an El Dorado County Sheriff’s Office news release.

The caller was separated from his brother during the attack and suffered “traumatic injuries” to his face, according to the release. Deputies and paramedics administered aid and took him to a hospital for further treatment.

After deputies searched for the missing brother, they found him on the ground next to the crouched mountain lion around 1:46 p.m., the release said.

The deputies fired their weapons to ward off the mountain lion so they could get to the brother, according to the release.

“Deputies discharged their firearms in order to scare the mountain lion off so they could render medical aid,” the release read. When they reached him, they realized the 21-year-old had died, according to the sheriff’s office.

“A fatality like this is extremely rare,” Kyle Parker, a spokesperson for the El Dorado County Sheriff’s Office, told CNN affiliate KCRA.

The mountain lion was later found by wardens from the California Department of Fish and Wildlife and the El Dorado County trapper, according to Parker.

“The mountain lion was dispatched, and the body of the mountain lion was collected for further examination,” he said.

The California Department of Fish and Wildlife will now try to find out why this attack happened, according to Parker.

Mountain lion attacks on humans are rare, according to the state agency. This is the first fatal mountain lion attack in California in 30 years.

The last recorded fatal mountain lion attack in El Dorado County was reported in April 1994, according to the California Department of Fish and Wildlife. A 40-year-old woman died after an attack in the Auburn State Recreation Area.

Since 1890, there have been fewer than 50 reported mountain lion attacks on humans in California, and only six of those have been fatal, according to California wildlife officials. In most cases, the person was alone when the attack occurred, according to the department.

CNN has sought more information about the attack from authorities.
