The Texas Department of Public Safety (DPS) has increased the reward of up to $6,000 for any information that leads to the arrest of those responsible for the 1988 murder of Courtney Clayton before next month's featured cold case is announced.

On Sept. 12, 1988, 7-year-old Clayton was abducted from near her home in Stamford. (Stamford is located in Jones County, approximately 40 miles north of Abilene.) Clayton was last seen walking to a small store, about a block from her home, to buy a soft drink.

"Despite an immediate and extensive search, the second grader’s remains were not discovered until six months later on Easter Sunday by hunters in Shackelford County, about 50 miles away near the small town of Moran," according to DPS. Clayton was identified by the hair from a hairbrush her parents had kept.

To be eligible for the cash rewards, tipsters must provide information to authorities by calling the Crime Stoppers hotline at 1-800-252-TIPS (8477). All tips are anonymous.

Individuals also can submit information through the Texas Ranger Cold Case website or by contacting us at 1-800-346-3243 (DPS Missing Persons Hotline).
