Heriberto Nony Herrera, 40, was last seen in Las Vegas on May 14, 2010. The day he disappeared followed a severe psychotic episode the previous month; he had recently been diagnosed with bipolar disorder, schizoaffective disorder, and depression with psychotic features. His wife left their Summerlin home that morning with their twin sons after growing concerned about his behavior. Herrera reported his family missing and later tried to contact his sister. Police escorted his wife back to the house that day and saw Herrera; he phoned his wife that evening to say he loved her and the children, and that call is the last known contact.

On June 15, 2010, Herrera’s vehicle was found abandoned in a parking lot near the Mary Jane Falls trailhead on Mount Charleston. Inside were a packed suitcase, his medication, and a case of bottled water with one bottle missing. In August 2011 hikers discovered a box at high elevation containing his financial records, cash, and many credit cards; authorities questioned whether Herrera, who had asthma and limited hiking experience, could have reached that steep area. Searches on Mount Charleston by police and volunteers produced no further evidence. His family maintains he would not have voluntarily abandoned his children and remains concerned for his safety.

Did anyone on Mount Charleston in May or June 2010 see a man matching Herrera’s description or his vehicle near the Mary Jane Falls trailhead?
