A 79-YEAR-OLD MAN HAS BEEN CHARGED WITH A 45-YEAR-OLD MURDER AFTER POLICE MATCHED DNA FROM HIS TRASH TO BLOOD FOUND ON THE VICTIM’S CLOTHING INVESTIGATORS TESTED DISCARDED BARBECUE SAUCE AND SODA BOTTLES TO CRACK THE COLD CASE

The trash on your curb usually contains nothing more than mundane leftovers and junk mail. For one Colorado man, however, a pair of discarded soda bottles became the ultimate witness to a crime committed four decades ago. A 79-year-old man now faces the consequences of a cold case that refused to stay buried, proving that time is no longer a shield against forensic science.

In 1981, the city of Grapevine, Texas, was rocked by the brutal discovery of 35-year-old Beverly “Casey” Bruneau. The Braniff Airlines flight attendant was found inside her own home with an electrical cord around her neck. Her boyfriend discovered her body after she failed to answer his calls, a scene marked by clear evidence of a violent struggle. Despite visible blood on her nightgown and face, the technology of the early eighties could not point to a specific killer. The case eventually went cold, leaving a family without answers for nearly half a century.

The breakthrough finally arrived in 2026. Investigators in Texas worked with the Larimer County Sheriff’s Office in Colorado to quietly monitor Larry Dean Brown. Officers performed a tactical trash pull outside Brown’s residence, seizing two soda bottles he had thrown away. When laboratory technicians at the University of North Texas compared the biological material on those bottles to the decades-old bloodstains found on the victim’s clothing, they found a match. The results indicated Brown could not be excluded as the source of the DNA, leading to a murder indictment by a Tarrant County grand jury.

The link between the victim and the suspect was not random. Brown was the husband of Bruneau’s best friend and former roommate. During the initial investigation in 1981, detectives noted several red flags. Brown appeared evasive during questioning and sported a fresh, raw injury under his right thumbnail. At the time, he claimed it was an injury from his construction job. More importantly, the group was embroiled in a messy financial conflict involving a DFW-area property.

A house co-owned by Bruneau and Brown’s wife had been severely damaged by fires in late 1980. Investigators suspected arson, though no charges were filed then. Brown, a pilot who had recently been laid off, allegedly pressured Bruneau to sign off on inflated insurance claims to funnel more money into his own construction company. This financial friction, combined with the physical evidence, painted a picture of a man desperate for a payout.

This case highlights the growing trend of “trash pulls” and genetic genealogy in modern policing. Since the 1988 Supreme Court ruling in California v. Greenwood, law enforcement has generally been permitted to search trash left on a curb without a warrant. The court argued that people have no “reasonable expectation of privacy” for items they voluntarily discard in a public place. This legal precedent has become a nightmare for aging criminals who believed their secrets were safe in the landfill.

Similar tactics were famously used to capture the Golden State Killer, where biological remnants from a car door handle and a piece of tissue led to an arrest. For these cold case detectives, the work never truly stops. In 2010, the Tarrant County team had already begun re-processing the nightgown, successfully extracting a male DNA profile that was entered into the CODIS database. While that initial search yielded no hits, the persistence of a lone Grapevine detective in 2025 reignited the trail.

The shift in forensic methodology from the 1980s to today is staggering. In the year the murder happened, DNA profiling was still years away from being a courtroom reality. Today, even microscopic skin cells or a drop of dried blood can be sequenced. Brown was extradited to Texas and booked into the Tarrant County Jail this year, where he awaits further legal proceedings for the strangulation death.

As forensic technology continues to advance, the “perfect crime” is becoming an extinct concept. Families who have spent decades in mourning are finally seeing the suspects they once knew brought to justice. For Larry Dean Brown, the simple act of finishing a soda and throwing away the bottle provided the final piece of a puzzle that took 44 years to complete. The message to cold case suspects is clear: your past is only one garbage pickup away from catching up with you.
