The Throat-Slash Murders: The Chilling Tale of David Allen Lucas

A Serial Killer in San Diego

The quiet neighborhoods of San Diego County, California, harbored a terrifying secret between 1979 and 1984. A series of brutal murders, characterized by the slashing of throats, gripped the region in fear. The man behind these heinous crimes was David Allen Lucas, an American serial killer who was ultimately convicted for his gruesome acts. Born in 1956 in the Philippines on an American military base, Lucas's journey from a troubled childhood to death row is as chilling as it is complex.

Early Life and Troubling Beginnings

David Allen Lucas was one of three children born to naval officer Clarence Lucas and Patricia Katzenmeier. His early life was marked by turmoil and abuse. The family returned to the United States when David was young, settling in an environment fraught with violence. David suffered from bronchial asthma and nocturnal enuresis, conditions that were compounded by his father's abusive behavior. Clarence Lucas was known for his violent outbursts and would often beat his children and wife with objects like a belt or telephone cable. The Lucas children, especially David, endured severe physical and emotional abuse. In one particularly harrowing incident, David's sister was forced to eat her vomit. The family dynamic shattered in 1971 when Patricia divorced Clarence and left with the children. By 1973, David was arrested for raping a 21-year-old maid, a crime that foreshadowed his future violence.

The Murders Begin: Suzanne and Colin Jacobs

The terror began on May 4, 1979, with the murders of Suzanne Camille Jacobs and her three-year-old son, Colin. Living in Normal Heights, Suzanne's husband, Michael, left for work early that morning, unaware of the horror that would unfold. A neighbor, Margaret Harris, noticed a dark maroon sports car outside the Jacobs' home later that morning. When calls to Suzanne went unanswered, concern grew. Michael returned home that evening to a nightmare—finding his son dead in the hallway. Neighbors discovered Suzanne's body in the bedroom, signifying a brutal struggle. Investigators found blood throughout the house and a piece of paper with cryptic messages, "Love Insurance" and "280–1700." Forensic analysis revealed that both mother and child had their throats slashed with brutal force, and the killer left behind bloody footprints from Vibram-soled shoes, all indicating a lone perpetrator.

The Trail of Death Continues: Gayle Garcia and Jodie Santiago

On December 8, 1981, the pattern of violence continued with the murder of 29-year-old realtor Gayle Roberta Garcia. She was found dead in a vacant Spring Valley property, her throat cut in a manner reminiscent of the earlier murders. The similarities did not go unnoticed, and investigators began to suspect a connection.

In a chilling twist, Lucas's violence did not stop at murder. On June 8, 1984, he attacked Jodie Santiago Robertson, a visitor from Seattle. After leaving a restaurant that evening, Santiago was accosted by Lucas, who forced her into his car, took her home, and raped her. He attempted to kill her by slitting her throat, leaving her for dead in some bushes. Miraculously, Santiago survived but suffered severe injuries, including damage to her vocal cords and jugular vein. Her detailed description of Lucas and his car would later play a crucial role in his capture.

The Double Murder of Rhonda Strang and Amber Fisher

The violence escalated on August 3, 1984, when Lucas allegedly killed 24-year-old Rhonda Strang and three-year-old Amber Fisher. Rhonda, who was babysitting Amber in Lakeside, was found dead alongside the child. Rhonda's tumultuous relationship with her husband, Robert Strang, a known drug user, added complexity to the investigation. Robert was cleared as a suspect, leading detectives to suspect Lucas, who had ties to the Strang family through drug transactions.

The Final Murder: Anne Swanke

Lucas's last known murder occurred on November 19, 1984. Anne Catherine Swanke, a 22-year-old student, disappeared after her car ran out of gas near La Mesa. Her body was discovered days later, two miles from Lucas's home. She was found partially undressed, with her throat cut and a dog chain around her neck.

Arrest and Legal Proceedings

The arrest of David Allen Lucas in late 1984 marked a turning point in the investigation. Charged with the murders of Rhonda Strang, Amber Fisher, Anne Swanke, and the assault on Jodie Santiago, Lucas was also linked to the killings of Suzanne and Colin Jacobs through additional indictments. Initially, another man, Johnny Massingale, had been wrongfully arrested for the Jacobs murders and spent ten months in jail before Lucas's involvement was confirmed.

The Trial: A Fight for Justice

The trial of David Allen Lucas began in early 1986, becoming one of the most prolonged in San Diego's history. The district attorney consolidated multiple charges into a single trial, which commenced in early 1987. Lucas's defense argued for Massingale's guilt, but the evidence against Lucas was overwhelming.

Witnesses like Jodie Santiago provided crucial testimonies, and forensic evidence linked Lucas to the crimes. Despite the defense's attempts to deflect blame, Lucas was found guilty of multiple murders and sentenced to death. He remains on death row at San Quentin State Prison, a grim testament to his violent legacy.
