Yolanda McClary, Kelly Siegler

Former prosecutor Kelly Siegler and crime scene investigator Yolanda McClary try to solve a nearly 30-year-old murder on Friday's episode of TNT's Cold Justice.

Traveling to Alamogordo, New Mexico, the pair looks into the case of Margie Pointer, who disappeared on Nov. 20, 1987. In 2004, her remains were found in a wooded area about 20 miles from her home, but no cause of death was ever established.

Who was the mysterious man Margie was seen having breakfast with on the morning she disappeared? And was he involved in her death?
