This week marks the 20th anniversary of what some called “one of the greatest unsolved cases” in Ellis County.

On March 19, 1994, former Lancaster resident Robbie Jean Biggar was reported missing. A day later, her grandson Kasey Robers was found in a car in front of a Red Oak apartment complex, deceased from heat exhaustion, previous Waxahachie Daily Light articles stated.

Two days later, on March 22, 1994, Biggar was found on the side of an Ellis County road, on the grounds of what was the Superconducting Super Collider. The Dallas County Medical Examiner’s Office ruled Biggar died of blunt force trauma to the head.

More than four law enforcement agencies investigated the case. However, leads in what was ruled as a double homicide began to fade three days later, a 1994 Waxahachie Daily Light article stated.

Investigators remained confident they would crack the case, according to previous Waxahachie Daily Light articles. Yet, it wouldn’t be until 2009, that the lead agency on the investigation would make an arrest.

The Ellis County Sheriff’s Office arrested Biggar’s boyfriend at the time, Larry Samples, and Galen Boyd, an acquaintance of Samples', previous Waxahachie Daily Light articles stated.

However, when the Ellis County District Attorney at the time ruled in 2010 there wasn’t enough concrete evidence to indict the two men, they were released.

Four years later, the case still isn’t closed. The Waxahachie Daily Light is going to give you an inside look as to why this has been “one of the greatest unsolved cases” in the county, and just how come this case has been so difficult to close.

Look for the articles in upcoming issues of the Waxahachie Daily Light, or on, as we walk you through the history of the case of Robbie Jean Biggar and her grandson Kasey Roberts.
