Linda Henning was born on October 10, 1953, in Hollywood, California. She grew up in an urban environment with the energy of a bustling city. After completing high school, Linda pursued a career as a fashion model. Her modeling career was successful, which led her to become a fashion designer later on.

In 1999, Linda met a man named Diazien Hossencofft. Their relationship quickly escalated, and Linda ended her engagement with her fiancé to be with Diazien. Both shared a keen interest in topics such as government conspiracy theories and UFOs. 

On September 10, 1999, Girly Chew did not come to work. Her co-workers became worried and reported her missing that same day. The main suspect in her case was Diazien Hossencofft; he left for Charleston, South Carolina, on the morning of September 10. Investigators then looked into Girly's apartment and Diazien's girlfriend, Linda Henning. In Girly's apartment, police noticed a strong smell of bleach and found a significant amount of blood using luminol.

After searching Girly's apartment, police questioned Linda Henning, who claimed she thought Diazien was a doctor and that she had no knowledge of Girly's disappearance. Linda later told a grand jury that she did not know Diazien's wife, but investigators proved she was lying. They found out that Linda had banked at the same branch where Girly worked, and Girly had served as her teller. In October 1999, Linda Henning was charged with perjury for lying to the grand jury.

Investigators found a ninja sword in the attic of Linda’s home, which had been purchased on the same day Girly was reported missing. Days after Girly's disappearance, her clothing was discovered on a tarpaulin in Belen, New Mexico. Along with her clothes, police located duct tape that had Linda Henning's hair on it. Both Linda Henning and Diazien Hossencofft were indicted and charged with murder.

In January 2002, in an effort to avoid the death penalty, Diazien Hossencofft pleaded guilty to his wife's murder. In exchange for his plea, he received a life sentence plus 61 years to be served in Wyoming State Penitentiary. Linda Henning's murder trial began in September 2002. This was significant because she became the first woman in New Mexico history to face a death penalty trial. Some of Linda's friends thought she had been manipulated and controlled by Diazien. During the trial, witnesses observed Linda’s unusual behavior while forensic experts testified.

Defense attorneys for Linda called Diazien to testify on her behalf. On the stand, he claimed that he had planned Girly's murder and that Linda was innocent. He accused another man, Bill Miller, of being Girly's true killer. Bill Miller faced charges but was only charged with tampering with evidence. Regarding blood found in Girly's apartment, Diazien stated that he had planted Linda's blood there to confuse the investigation. Linda's attorneys argued that Diazien intended to frame her.

On October 25, 2002, Linda Henning was convicted of first-degree murder, along with kidnapping, conspiracy to kidnap, tampering with evidence, and four counts of perjury. Due to the seriousness of the crimes, Linda faced the death penalty. However, at her sentencing on April 18, 2003, she was not given a death sentence. Instead, she received a 73-year prison term.

Bill Miller, connected to the case, was given one year of probation for his involvement. Linda Henning's perjury convictions were later overturned in 2010 by the New Mexico Supreme Court, but her other convictions and sentence were upheld. The murder case of Girly Chew has been featured on several television programs and in publications. In January 2020, Diazien Hossencofft sought to have his life sentence vacated, claiming that evidence had been hidden that could prove both he and Linda Henning innocent.
