Catherine O'Brien Kalberer, a dedicated 33-year-old female teacher, was on the verge of a new chapter in her career when her life was brutally extinguished. On January 28, 1970, she was expected for her first day at a new position at Takoma Park Junior High School in Washington, D.C., but she never arrived. Her failure to appear prompted concern, leading to a grim discovery that would haunt the community of Bethesda, Maryland, for decades.
The day before, Catherine had been reported
missing. The search ended when her body was found in the back seat of a neighbor's car parked right in front of her own apartment building. The scene inside her residence told a story of unimaginable violence. Bloodstains marked the apartment, and a bloodied knife was left behind. An autopsy would later reveal the horrific extent of her injuries; she had been stabbed and slashed 124 times in her chest and legs, and her throat had been cut. Investigators believed she was ambushed, possibly struck on the head as she returned home from grocery shopping, then dragged into her kitchen where the savage attack began.
The ferocity of the murder sent a wave of fear through the Washington, D.C. metropolitan area. Catherine's killing came just twelve days after the murder of 14-year-old Sherry Bristol Kennedy in the nearby community of Potomac. The brutality of both crimes led to public speculation that a serial killer, later dubbed "The Bethesda Butcher" and "The Beltway Butcher," was at large. Suspicion soon fell on a local man named Thomas Francis Edwards, who had a history of violence. In November 1970, news outlets reported that an unnamed suspect had been detained, with police claiming fingerprint evidence linked him to the murders.
Despite the strong suspicion, Edwards was never tried for Catherine's murder in the 1970s. He was eventually released and moved to California, where his violent tendencies resurfaced with tragic consequences. In September 1981, Edwards shot two 12-year-old girls, Vanessa Iberri and Kelly Cartier, in the Cleveland National Forest. Vanessa died from her injuries, while Kelly survived. A witness to the attack provided Edwards' license plate number, leading to his arrest in College Park, Maryland. Extradited to California, he was convicted of Vanessa's murder and the attempted murder of Kelly. He was sentenced to death in 1986.
For years, Catherine Kalberer's case remained officially unsolved. Detectives with the Montgomery County Police Department, however, never gave up. Starting in 1985, they began to re-examine the evidence against Edwards. A crucial piece was a small bloodstain on a green army jacket found in his home during the initial 1970 investigation. With advancements in forensic science, investigators were finally able to test the stain using modern DNA technology.
The results provided the breakthrough they had sought for so long. The DNA from the bloodstain was a match to Sherry Kennedy. While a direct DNA link to Catherine's case was not specified, the evidence connecting Edwards to the Kennedy murder was strong enough for authorities to officially attribute both killings to him. In January 2012, more than four decades after her death, Catherine O'Brien Kalberer's case was finally closed. Her killer, Thomas Francis Edwards, had already died of natural causes on California's death row on February 14, 2009, having never been brought to justice in Maryland for the lives he destroyed there.
