Delaware County Sheriff's Office officials are searching for a missing Grove couple. 

Brianna Gideon, 16, and William D. "Billy" Berry, 20, both of Grove, have been missing since the late evening hours of Saturday, March 3, or the early morning hours of Sunday, March 4.

The couple, who were in a dating relationship, are believed to be together, according to Captain Gayle Wells, with the sheriff's office. 

Gideon is described as a 4-foot, 11-inch tall, female, with reddish brown hair and blue eyes, and weighing 100 pounds. 

Berry is around 5-foot, 5-inches tall, with dark hair and dark eyes. In some pictures he is shown wearing a mustache.

Authorities believe the pair may be traveling in Berry's 2004 greenish blue or light hunter green Nissan X-terra with the Oklahoma license plate CM 9380.

Wells said a "be-on-the-lookout" bulletin has been issued throughout the midwest for Berry and his vehicle. 

Wells said officials have "run down all of the leads" available at this time. He indicated cell phone records and laptops were also being searched for possible clues to the couple's location.

Persons with information concerning Gideon or Berry are asked to contact the Delaware County Sheriff's Office at 918-253-4531.
