Deborah Sue Williamson's house

This is the house where Deborah Sue Agnew Williamson was murdered.

It is located at 1115 82nd Street in Lubbock, Texas.

Williamson was supposed to meet her husband, Doug, at his workplace on the evening of August 24th, 1975. However, she never showed up.

When her husband called their house at 10 p.m. to inquire about the delay, she failed to pick up the phone.

At approximately 1 a.m., Doug returned home from his job at a local pizza parlor and found his wife's body outside in the carport.

She had been stabbed 17 times.

The authorities estimated that the attack took place at around 9 p.m.

Williamson was an 18-year-old newlywed who had tied the knot with Doug just two months prior.

Doug's albi checked out, and he also passed a polygraph.

Once he was cleared as a suspect, the police struggled to find any leads, and the case went cold for nine years.

In 1984, a serial killer named Henry Lee Lucas told investigators that he had murdered Williamson. Although the authorities believed that they had finally caught their man, Williamson's parents were extremely skeptical about his confession.

At the time, Lucas was eagerly taking credit for every cold case that was being put in front of him. By that point, he had already confessed to dozens of murders across multiple states.

Sensing that something wasn't quite right about Lucas' story, Williamson's mother and stepfather decided to investigate the matter themselves.

Not long after, they found documents that proved he wasn't in Texas at the time of their daughter's murder.

Consequently, the case against Lucas was dropped.

Later, he admitted that he had lied about his involvement.

The murder of Deborah Sue Williamson remains unsolved to this day.

It is still an active case.
