Melissa Suzanne Johnson, 34, was last seen in Sonora, California, in August 2016 and was not reported missing until June 13, 2019 — a nearly three-year gap that investigators say has complicated the inquiry. She had not been in contact with family during that interval. Johnson was described as a white female, blonde hair, hazel eyes, 5 feet 5 inches to 5 feet 6 inches tall, 125 to 150 pounds, with a tribal tattoo on her lower back and a scar above her left eye.

She may also have used the last names McCormick or Silverman and was known to frequent Modesto, California, and Wichita County, Texas. Few details about her final movements are available: authorities have not released what she was wearing, who last saw her, or precise last known locations.

Anyone with information about Melissa’s whereabouts is asked to contact the Sonora Police Department or the Tuolumne County Sheriff’s Office.
