BEND, OR -- The Deschutes County Sheriff's Office is searching for a 60-year-old Bend woman who may be suffering from a mental illness. Susan Lewis' vehicle was found near Sizemore Road and Couch Market Road, northwest of Bend. A citizen reported Thursday that it was parked there for about a week, with no one seen around it.

Investigators have determined Lewis returned to Central Oregon Saturday, April 15 after spending an extended amount of time out of state for medical treatment. She left a voice mail asking a friend where she could find her own house keys. The Sheriff's Office says her car was found about two miles from her home. She has a cell phone but it's turned off.

They're asking for the public's help to find Lewis. She's 5'2" tall, about 115 pounds, with brown hair and blue eyes. There is no clothing description. Anyone who has seen her or remembers seeing her white 2007 Volkswagen Passat is asked to call non emergency dispatch at 541-693-6911.

UPDATE: Deschutes County Search and Rescue found Lewis' body on Saturday, while combing 500 acres near where her car was discovered. The investigation is ongoing, but preliminary information indicates she died of a self-inflicted injury.
