Authorities in Jefferson County, Texas are searching for a 14-year-old girl missing for over a month who may be in danger.

Sharon West was last seen around 2:00 am on July 30 at a friend’s home in Fannett. She was staying with the friend’s family at the time. According to the Jefferson County Sheriff’s Office, they believe her cell phone was last used a few hours later to send text messages from the nearby Seabreeze Soccer Fields area. Sharon has not been heard from since.

A cell phone was found at the soccer fields on August 30, but Deputy Rod Carroll said investigators have determined that it was not Sharon’s.

Early in the investigation, authorities conducted extensive ground and aerial searches, deployed search dogs and questioned registered sex offenders in the county, but Sharon’s whereabouts and the circumstances surrounding her disappearance remain a mystery.

Carroll said police have questioned Sharon’s boyfriend and are continuing to follow leads, but he would not comment on whether any items of evidentiary value have been uncovered. Besides her phone, none of her belongings were missing.

Sharon’s mother and a private investigator working with the family have said it would be out of character for her to stay out of contact for so long. She is currently classified as a “missing endangered” juvenile.

According to Carroll, the National Center for Missing and Exploited Children has been assisting with the investigation and a $1,000 reward has been posted by Beaumont Crime Stoppers. Anyone with information about Sharon West’s disappearance is asked to contact the Jefferson County Sheriff’s Office at 409-835-8411 or Crime Stoppers at 409-833-TIPS.
