SANTA ROSA, Calif. -- A Guerneville man will undergo a mental health evaluation over the next 90 days before he is sentenced in Sonoma County Superior Court for an assault with a bow and arrow in January.

Judge Gary Medvigy ordered the tests Thursday morning when Gallon was scheduled to be sentenced. The judge acknowledged Gallon's statements of remorse in a probation department report but also said he is concerned about public safety. The probation department recommended the evaluation.

Deputy District Attorney Rosanne Darling said Gallon also made some "strange and troubling statements" in the probation report.

Medvigy found Gallon, who will turn 30 on Sunday, guilty of assault with a deadly weapon after a two-day non-jury trial in June. Gallon had been scheduled to be sentenced to a maximum four-year prison term today, Darling said.

Gallon fired the arrow from the third floor balcony of a residence on Mill Street on Jan 27. The arrow pierced the top a convertible that was parked 60-100 feet across the street and struck James McNeil of Monte Rio in the skull. He suffered a nearly inch-long cut.

Defense attorney Gerald Villarreal said this morning he was not surprised the judge asked for a more thorough mental health evaluation at San Quentin State Prison before Gallon is sentenced.

Villarreal said Gallon was bothered by the loud behavior of people habitually doing drugs in vehicles near his home.

After reviewing photos taken at the scene and the arrow itself during the trial, Medvigy ruled the bow and arrow were works of art and a substantial weapon, and the arrow was spinning when it pierced the fabric of the Mazda convertible's roof.

"Fortunately the arrow did not go into the neck or another soft area. Luckily it hit the skull," he said in June.

The Sonoma County Sheriff's Department's SWAT unit responded to the shooting and staked out the area for more than 24 hours before searching the residence where the suspect was believed to be hiding.

The sheriff's department at the time said Gallon was a self-taught survivalist and should be considered armed and dangerous.

Gallon was not there and he surrendered to the sheriff's department on March 4.
