Terry Allen Langford was born on May 18, 1966, in Lebanon, Kentucky. His early life is not well documented. He grew up in a small town, and little is known about his family or his childhood experiences. As he became an adult, he lived a nomadic lifestyle, often drifting between different places. At one point, he made his home in Raleigh, North Carolina.

In the summer of 1987, he was involved in legal trouble and was convicted of two misdemeanors: forgery and tampering with a motor vehicle. Despite the seriousness of these charges, he did not serve any jail time for them.

In June 1988, Terry Allen Langford took a bus to Ovando, Montana. He hiked north into the mountains and ended up near the property of Ned and Celene Blackwood. For several days, he observed their activities from a distance. On July 5, 1988, he entered their home, killed them, and took their belongings.

After the murders, Langford traveled to Jeffersonville, Indiana. He checked into a motel. The next day, he threatened a maid with a knife when she entered his room. He escaped from the motel and left a bag in a nearby wooded area. This bag contained the stolen guns of the Blackwoods. A check on the guns revealed they belonged to the couple he had murdered. Langford was later tracked down and arrested.

Langford was found guilty of the Blackwoods’ murders and received a death sentence on January 26, 1989. While in Montana State Prison, he was involved in a riot on September 22, 1991. During this riot, he killed a fellow inmate, which led to another conviction for deliberate homicide and a life sentence without parole. He was acquitted of four other homicide charges.

Langford waived his appeals and was executed by lethal injection on February 24, 1998, at the Montana State Prison. He did not make a final statement. At 31 years old, he became the youngest person executed in Montana since capital punishment was reinstated in 1976. Langford was only the second of three people executed in Montana since that time.
