Grapevine, Texas — More than four decades after a Texas woman was found strangled inside her home, investigators say advances in DNA technology have led to the arrest of a 79-year-old man, marking a major breakthrough in a homicide investigation that had remained unsolved since 1981.
The Grapevine Police Department announced that Larry Dean Brown, 79, has been arrested on a charge of murder intentionally causing death after being extradited from Colorado to Texas.
Authorities say the arrest is connected to the killing of 35-year-old Beverly Bruneau, whose death shocked investigators more than 44 years ago.
Woman Was Found Dead Inside Her Home in 1981
According to investigators, Bruneau’s boyfriend returned home from work on February 13, 1981, and discovered her lying on the living room floor.
Authorities said an electrical cord was wrapped around her neck, and she had visible blood on her face.
Investigators also found evidence suggesting a violent struggle had taken place inside the residence.
An autopsy later determined that Bruneau died from strangulation, with investigators believing the killing occurred sometime during the mid-morning hours before her body was discovered.
Investigation Focused on Insurance Dispute
Court records indicate investigators interviewed Brown during the original investigation because his wife, Thelma Brown, was one of Bruneau’s closest friends.
According to the arrest affidavit, Bruneau and Thelma Brown jointly owned a home in Dallas that had previously been damaged by fire.
Investigators allege Larry Dean Brown pressured Bruneau to sign insurance documents containing inflated repair costs.
Authorities say Bruneau refused to sign the paperwork.
According to the affidavit, investigators later determined that Thelma Brown allegedly forged Bruneau’s signature on insurance documents after Bruneau’s death.
The allegations outlined in the affidavit have not been proven in court.
DNA Evidence Revived the Decades-Old Cold Case
The investigation remained unsolved for nearly 30 years before forensic experts reexamined evidence collected from the crime scene.
In 2010, investigators identified an unknown male DNA profile, but no match was found in the FBI’s Combined DNA Index System (CODIS).
Years later, detectives reopened the investigation and worked with the Larimer County Sheriff’s Office in Colorado, where Brown was living.
According to investigators, detectives collected discarded soda bottles from Brown’s trash to obtain a DNA sample for comparison.
Authorities say laboratory testing indicated Brown could not be excluded as the source of blood found on Bruneau’s nightgown, leading to his arrest.
Additional Testing Still Pending
Police emphasized that the investigation remains active and that additional forensic testing, including confirmatory DNA analysis, is still pending.
“The arrest follows an extensive investigation by detectives and represents a significant development in the case,” the Grapevine Police Department said in a statement.
Investigators added that they will release additional information once further laboratory testing has been completed.
Court records show Brown’s attorney has filed a motion seeking to reduce his $2 million bond, but reports indicate the request was denied, and Brown remained in custody as of July 15.
Although the arrest marks a significant milestone in the decades-old investigation, prosecutors must still present the evidence in court, where Brown is presumed innocent unless and until proven guilty.
