Who is Jose Montes-Herrera?

COPS in Nevada have launched an exhaustive search for 37-year-old Jose Montes-Herrera and his 11-year-old son Eden.

The boy's 8-year-old half-brother was found dead by a hiker on May 28.

Jose Montes-Herrera, a Las Vegas resident, and his son Eden are both missing, according to authorities.

"They both might possibly be in severe emotional distress and in need of medical assistance," an alert from police reads, according to KTNV.

The body of the 8-year-old boy was found near Route 160, the main highway between Las Vegas and Pahrump, the station reported.

His mother made a positive identification after the Clark County Coroner showed her photos.

A cause of death for the child has not been given but cops say he was a homicide victim.

Both children were seen with their father on the night before the younger sibling was found dead.

Eden, his missing older brother, is 5-feet tall and 110 pounds, and has brown hair and brown eyes, according to KTNV.

Authorities believe Montes-Herrera is driving a 2015 white GMC pickup truck with Nevada license plate LV UOOX.
