Sonoma County sheriff's detectives have arrested two Santa Rosa residents following a Nov. 2 stabbing on a rural road.

The suspects, Glenn Bates, 29, and Regina Morgan, 33, were arrested without incident at a residence on Francisco Avenue, sheriff's officials said.

Detectives are still trying to identify a motive for the stabbing on Porter Creek Road north of Santa Rosa. They have not released the identity of the victim due to safety issues.

Last Friday, shortly after 1:30 a.m., a passer-by found the wounded man on the shoulder of the road near Mark West Springs Lodge and Leslie Road.

The passer-by called 911, but an ambulance transporting a patient from Lake County encountered the scene while driving to a Santa Rosa hospital.

The victim's injuries were initially considered life-threatening, but he has been recovering from his wounds at a local hospital, officials said. Sheriff's officials said the man has been cooperating with the investigation, though he has given varying stories about what happened.

Bates was charged with attempted homicide and violation of parole and Morgan was charged with possession of a controlled substance and also with violation of probation. Both were held without bail, due to probation violations linked to previous theft cases.

The case is still under investigation. Anyone with information about the incident is asked to contact Detective Gary Freitas at 565-2185.
