A missing 28-year-old Sacramento County woman was found dead from a gunshot wound in Placer County Thursday, according to the Sacramento County Sheriff’s Department.

On Tuesday, Janet Mejia was reported missing by her roommate, who said Mejia was last seen around 9 a.m. when Mejia left her residence in the 7200 block of Pepperwood Knoll Lane in the north area of Sacramento County. Detectives were initially told that Mejia had a doctor’s appointment in Stockton that day but never arrived, the sheriff's department said.

On Wednesday afternoon, deputies say they located Mejia’s vehicle abandoned in the Arden-Arcade area. Family and friends told authorities that Mejia’s disappearance was "out of the ordinary for her, and she was usually in constant contact with her family."

At approximately 7 p.m. on Thursday, homicide investigators located an unidentified deceased female just off the roadway in the area of Watt Avenue and Dyer Lane in Placer County, the sheriff's department said.

The Sacramento County Coroner’s Office says they conducted an autopsy, and positively identified the victim as Mejia. The preliminary findings showed Mejia suffered from a gunshot wound and was a victim of a homicide.

The homicide detectives say they do not believe this was a random murder. A person of interest is currently in custody on unrelated criminal charges pending forensic testing.
