The Cookie Monster KILLER: Harrison Frank Graham

Unraveling the Dark Crimes of Harrison Frank Graham

By Sally APublished about a month ago 3 min read

Harrison Frank Graham, born on September 9, 1959, in Philadelphia, Pennsylvania, was better known by his nickname, Marty. Graham's early life was marked by instability and hardship. Born to a young mother, Lillian Graham, who was just 16 at the time, he was placed into foster care by the age of two due to her inability to care for him. The foster care system subjected Marty to various forms of abuse, a sad but common reality for many in similar situations.

Early Life and Struggles

Marty's early years were fraught with instability as he bounced from one foster home to another until he was seven years old. He eventually found some stability with foster mother Pauline Williams, who provided him with a semblance of a loving environment. His biological mother, Lillian, who had four more children, was intermittently present in his life. At the age of 12, Marty was sent to Philadelphia General Hospital for a mental disorder, according to his mother. He stayed there until he was 14, dealing with significant mental health issues and developmental delays.

Later IQ tests revealed Marty's severe intellectual disabilities, scoring a 63, which indicated a significant intellectual disability. His cognitive abilities hovered around a third-grade level, making everyday life extremely challenging. He struggled to read and perform basic tasks, ultimately leading him to drop out of high school.

Descent into Darkness

After dropping out, Marty found solace and a sense of belonging on the streets, mingling with others who had mental health issues. It was during this time that he fell under the influence of a pimp, who took advantage of his vulnerabilities. This man introduced Marty to a life of drugs and exploitation, further complicating his mental state and contributing to his eventual descent into violence.

In his mid-teens, Marty moved back in with his mother, who had become deeply religious. Under her influence, he attempted to turn his life around, attending church and securing a job in construction. For a while, it seemed Marty was on a path to stability. He moved into his own place in a row of old, dilapidated houses in lower North Philadelphia, becoming a helpful figure in his community and even forming a long-term relationship with a woman named Robin.

The Emergence of Multiple Personalities

Despite the semblance of a stable life, Marty's untreated mental health issues began to surface in more severe ways. Diagnosed with Dissociative Identity Disorder (DID), Marty harbored multiple personalities: his primary self, Marty, a kind and helpful man; Junior, a childlike personality who found comfort in a Cookie Monster doll; and Frank, a violent and drug-addicted persona. These identities often clashed, with Frank emerging more frequently as Marty's drug use escalated.

The Murders Begin

The turning point came with the murder of his girlfriend, Robin, in 1986. Under the influence of drugs and Frank's violent persona, Marty strangled Robin during intercourse. Her murder set off a chain reaction, leading to the deaths of six more women between 1986 and 1987. Each murder followed a similar pattern: Marty would lure women to his apartment with promises of drugs and sex, only to strangle them in a drug-fueled frenzy.

The Horrifying Discovery

The stench of decay eventually led neighbors to complain to the landlord, prompting an investigation. When the landlord's son, Gregory, attempted to evict Marty, he barricaded himself in his apartment and escaped through a fire escape. Gregory called the police, who forcibly entered Marty's apartment, uncovering a scene of unimaginable horror. The apartment was filled with trash, filth, and the decomposing bodies of Marty's victims.

Police discovered seven bodies in various stages of decomposition, hidden under piles of trash, between mattresses, and in a closet. The conditions were so dire that identifying the victims was a significant challenge, requiring forensic experts to use dental records and skull reconstructions.

Marty's Arrest and Confession

After a week on the run, Marty contacted his mother, who convinced him to turn himself in. He was arrested on August 16, 1987, and during interrogation, he calmly confessed to the murders, providing a detailed ten-page account of his crimes. Marty claimed that he would "black out" during the murders, with Frank taking over, and would wake up next to the corpses with no memory of the killings.

The Trial and Sentencing

Marty was charged with seven counts of first-degree murder and seven counts of corpse abuse. Despite his mental health issues, the judge rejected his defense of insanity, ruling that Marty knew right from wrong. He was found guilty and initially sentenced to death. However, due to his intellectual disabilities, the death sentence was eventually overturned, and he was sentenced to seven consecutive life sentences.

The Aftermath

Marty Graham remains incarcerated, currently serving his sentence in a medium-security prison's special needs unit. Since his incarceration, he has been taking antipsychotic medications and has become an ordained minister, showing signs of improvement.

The story of Harrison Frank Graham, known as the Cookie Monster Killer, serves as a chilling reminder of the complexities of mental illness and the importance of early intervention and support for those in need.
