Kids at Hilltop Park in Amarillo found a woman's body. It was Aug. 5, 1997. She had been stabbed many times. She had also been sexually attacked. Her body had defensive wounds too. It took Texas Rangers and Amarillo police almost 30 years to find her killer. New DNA tests finally cracked the case.

The woman worked as a cook at a nursing home. She was a mom of four kids. She was last seen alive around 3 a.m. that day. Someone saw her near North Marrs Street. Just hours later, kids found her body in the park. Only a few hours passed between those two moments.

This case shows how new science can crack old crimes. Cold cases sit for years with no answers. Families wait just as long. Some wait for decades. They never learn what happened to someone they loved. This case shows DNA tests can solve a murder years later. That is true even after the killer has died. It also shows why police save old evidence for so long. A small sample from long ago can still solve a case today.

Police looked hard for the killer back in 1997. They checked every suspect they could find. None of them matched. The trail went cold. The case sat unsolved for almost 30 years. For most of that time, there were no new leads.

In February 2024, a Texas crime lab in Lubbock got a new lead. Lab workers built a DNA profile. They used evidence saved from the 1997 autopsy. They ran that DNA profile through CODIS. CODIS is a national DNA database. Police use it to catch criminals across the country. The test came back with a hit. The name was Jimmy Dale McClinton.

Police then drove to Buchanan Dam, Texas. That is where McClinton lived at the time. They got a court order for his DNA. A new lab test matched his DNA to the old evidence. He was a match.

Police dug deeper into his past. They found McClinton had a long history of knife attacks on women. Some of those attacks looked a lot like the Amarillo case. He had lived in Amarillo back when the murder happened. But police never even talked to him back then. Records show he was arrested many times. Those arrests happened between 1977 and 2014, in Amarillo and Waco.

For the next two years, police built a murder case against him. Amarillo police and Texas Rangers worked with state lawyers. But McClinton died in November 2025. He was 81 years old. He died before the case reached a grand jury.

McClinton is dead now, so no arrest will happen. The case is closed for good. Texas Rangers thanked Amarillo police and the crime lab. They praised years of hard work on the case.

This case shows why police save old evidence for so long. One sample saved almost 30 years ago gave a family some answers. It took new science and two more years of work to get there. It shows new DNA tools can still crack old crimes. Some families are still waiting on answers in other cold cases. This story shows time does not always run out.

This story happened far from South Texas, up in the Texas Panhandle. But El Tejano covers news from all over Texas, not just the Rio Grande Valley. Readers here often have family in other parts of the state. A case like this one still matters to them. It shows how far crime labs have come since 1997. Labs like the one in Lubbock can now build a full DNA profile from decades-old evidence. That kind of science is closing cases many people once thought would never be solved.
