The Ripper Crew: Chicago's Satanic Serial Killers
How four men terrorized Illinois with ritualistic murders between 1981 and 1982
Published June 6, 2025

Quick Facts
Between spring 1981 and fall 1982, four men terrorized the Chicago area with a campaign of ritualistic murder that left investigators searching for answers to one of Illinois's darkest crime sprees. The group—Robin Gecht, Edward Spreitzer, Andrew Kokoraleis, and his brother Thomas—became known as the Ripper Crew, a designation that reflected the extreme mutilation their victims endured.
The killings began in May 1981 with the abduction and murder of Linda Sutton, a 26-year-old single mother taken from Chicago. Her body was discovered roughly 10 days later in a field behind the Moonlit Motel, bearing the signature mark of the gang: her left breast had been amputated. She was found handcuffed and slashed. Sutton's death would mark the first confirmed victim in what police would come to understand as a coordinated series of attacks.
Just two weeks after Sutton's disappearance, another woman fell victim to the crew. Angel York, a prostitute, was abducted and mutilated while still alive before being thrown from a van. Her survival and ability to describe her attackers provided critical evidence, though the men's reign of terror continued undeterred. Throughout late 1981 and into 1982, prostitutes and other vulnerable women became targets. Sandra Delaware, a teenager, was abducted, strangled, and stabbed before her body was dumped in the Chicago River.
Timeline
Group's crimes begin in the Chicago area
In May 1981, the period begins that the investigation documents as the Ripper Crew's active period of crimes in Chicago and DuPage County, Illinois.
Documented period of crimes ends in October 1982
Authorities determine that the documented period of the group's crimes ends in October 1982, as the investigation intensifies.
Robin Gecht convicted – 120 years in prison
Robin Gecht is convicted by an Illinois state court of attempted murder, rape, aggravated kidnapping and sexual assault. Not convicted of murder.
Andrew Kokoraleis executed in Illinois
Andrew Kokoraleis is executed in 1999 in Illinois after being convicted of murder and sentenced to death. One of the state's last executions.
Thomas Kokoraleis released on parole in March 2019
Thomas Kokoraleis is released on parole in March 2019 after his life sentence was reduced to 70 years. The release sparks public debate in Illinois.
By May 1982, the pattern accelerated. Lorraine Borowski, a receptionist, was abducted before she could open her office in the Elmhurst suburb. She was raped and murdered, her body hidden for five months before discovery in a Clarendon Hills cemetery.
The crew's methods were horrifically consistent: abduction, sexual assault, ritualistic mutilation, and murder. Investigators learned the group used Gecht's attic as a self-styled "Satanic Chapel," where they performed rituals that included the amputation of victims' breasts. Alcohol and drugs featured heavily in these ceremonies. The violence extended beyond sexual motivation; it was performative, ceremonial, and deliberately prolonged.
On October 6, 1982, the crew committed their only known murder of a male victim. Rafael Tirado, a 28-year-old drug dealer, was killed in a random drive-by shooting at a phone booth while standing with friend Alberto Rosario, who survived the attack. Gecht fired the weapons in this instance, demonstrating the group's willingness to expand their violent repertoire beyond their established methodology.
By the time law enforcement moved in, the crew claimed responsibility for up to 20 murders, though investigators confirmed between 17 and 20 victims. The actual total remains uncertain, with many cases unsolved and bodies potentially undiscovered.
Arrest and prosecution followed, though justice came slowly. Thomas Kokoraleis pleaded guilty to Lorraine Borowski's murder and received a 70-year sentence. Remarkably, he was released on March 29, 2019, after serving only half his sentence—a decision that sparked controversy given the brutality of the crimes.
A chilling detail emerged during investigation: Robin Gecht had been employed at PDM Contractors, a business owned by John Wayne Gacy, one of America's most notorious serial killers. The connection raised questions about potential knowledge or involvement, though no direct link to Gacy's crimes was established.
The Ripper Crew case remains a stark reminder of the depths of human depravity and the vulnerability of marginalized populations—primarily sex workers and women in poverty—to predatory violence. Their crimes defined Chicago's criminal history and continue to haunt the communities affected by their rampage nearly four decades later.
