Reports of a man trying to hang himself near Penngrove Park in Petaluma led to a late-night search for the individual, who reportedly suffered from mental health issues and who sheriff's deputies never found, according to Lt. Tim Duke.

The sheriff's office received a report of a man trying to hang himself at around 11 p.m. Tuesday night, Duke said. Officials found a noose hanging from a tree, but not the man. Based on reports that the man had fled on foot and taken a gas can, among other supplies, with him, the sheriff's office mounted a helicopter search.

They looked for him for about an hour and a half, circling the area around Penngrove Park, before abandoning the search and asking for the man's parents to alert them if he returned home.

Duke added that officials would be following up with the family today to see if the man had returned.
