The city of Racine, Wisconsin, sits on the shores of Lake Michigan at the mouth of the Root River, 22 miles south of Milwaukee and about 60 miles north of Chicago.
It is a beautiful place to live and raise a family, but in 1973 it became the setting of one of the most haunting unsolved murders in its history: the case of Tina Davidson, a fifteen-year-old girl whose death still remains a mystery. At that time, the US was experiencing a pivotal historical phase: Watergate, international terrorism, the oil crisis, the Cold War, and a flood of illegal drugs.
These were the years of the Ted Bundy murders and other serial killers, but also the dawn of disco and the gay liberation movement a time of freedom and hidden danger, explored in Hitchhiking and Blood on the Asphalt: The Stolen Freedom of the 1970s
The Murder of Tina Davidson
1973 was a year to remember—one that sociologists consider the last of the “true” sixties.
The youth of Racine spent their days by the lake and, during the warm months, lit bonfires on weekend nights. Laughing, drinking, and smoking weed without a care was the primary goal, typical of every young American at the time.
It was also an era when hitchhiking was a common way to get around, acting with a fearlessness that bordered on irresponsibility—a phenomenon explored in Hitchhiking and Blood on the Asphalt: The Stolen Freedom of the 1970s—while ignoring the danger posed by serial killers, a term not yet in vogue, even though criminals like John Wayne Gacy or the Son of Sam were already active.
It was in this context that on the night between March 26 and 27, 1973, four days before her sixteenth birthday, a beautiful and troubled teenager named Tina Marie Davidson—known to be an avid hitchhiker—was found dead on the lakefront at 17th Street
Hers was a life lived on the edge, marked by school expulsions, drug use, an arrest, a long-vanished father, and a mother unable to manage her.
Tina was found completely naked, killed by two massive blows to the head and 61 stab wounds. The autopsy revealed that, although the wounds were numerous, they were only about a centimeter and a half deep, suggesting a small weapon such as a Boy Scout pocketknife.
Cases like this were not isolated in the 1970s, as shown in The Carla Walker Case: 46 Years to Justice, another brutal crime involving a young girl during that same decade.
The cause of death was identified as a massive hemorrhage caused by a thrust that pierced her heart. Although newspapers at the time reported that Tina had not been raped, this has since been debunked by those who have read the autopsy report—a document that is itself shrouded in mystery.
Reportedly, the autopsy file was untraceable for many years and was only recently rediscovered. The case of the rebel teenager remains unsolved but has entered the local lore of Racine; even today, residents referring to that era say, “Back when Tina Davidson was found dead.”
Cases like Tina’s are part of a larger pattern of unresolved crimes that continue to haunt investigators and communities alike, as seen in Glenyce McGowan: A 50-Year-Old Australian Mystery, another case where time has only deepened the mystery rather than resolved it.
The Investigation
Tina lived with her mother Katherine and her younger half-sister Bonnie at 2810 20th Street.
She had grown up without her father, who had left years earlier. Due to disciplinary issues, she had cycled through several schools; she wasn’t a “thug,” but she was defiant toward rules, leading to clashes with her mother and teachers.
She had been arrested in December 1972 for truancy and was forced to enroll at Horizon (also known as “The Academy”) at 1032 Grand Ave, a correctional school where attendance was mandatory to resolve her legal issues. She would have turned 16 the following Sunday, April 1st.
That Monday afternoon, after spending time in her room with a friend named Cloy (it was never clear if he was a boyfriend), Tina left the house with a duffel bag, telling her mother she had to return some clothes to a friend, Patricia. There is a discrepancy in the timeline between her sister and mother.
Bonnie reported that Tina left at 6:00 PM, while Katherine said she left at 7:00 PM to walk her friend part of the way (he usually had a car but had arrived on a bicycle), then returned and left for good with the bag around 7:30 PM.
That was the last time her mother saw her alive.
Cloy later reportedly said that he had told Tina that afternoon they should stop seeing each other as much because he had discovered she was a minor.
Tina did go to Patricia’s house, but Patricia wasn’t home.
Tina told Patricia’s mother she would meet her friends. Strangely, Patricia later claimed she didn’t remember if Tina had actually left the bag of clothes there an odd detail to forget on the day of her best friend’s death.
Tina refused a ride from her friend’s brothers, saying she would hitchhike, but instead went to the home of two other friends in the same neighborhood. She stayed there for about an hour, delivering a 45rpm record with the haunting title “Killing Me Softly with His Song.”
Around 9:00 PM, she left, stating she was heading home rather than to Patricia’s. Her friends said she seemed in good spirits. From that moment on, her whereabouts are unknown. While Tina frequently hitchhiked, her friends noted she was usually cautious and rarely did so alone.
Tina did not return home that night, but her mother didn’t worry initially, as Tina often stayed overnight at friends’ houses without calling. She only learned of the death when police contacted her the next day around 4:00 PM.
Tina’s body was found on the morning of March 27 by a woman walking her child along the Lake Michigan shoreline, propped against a fence.
Tina had been raped and stabbed at least 61 times. Drag marks on her back and buttocks indicated she was killed elsewhere and dumped on the beach.
The cuts were shallow; she had 10 wounds on her back and was stabbed from her neck down to just below her breasts. Most wounds were to her chest. She had also been beaten, with bruises on her face, hands, knees, and buttocks. The medical examiner believed she was first knocked unconscious by a blow to the head.
The only suspect was a man aged 35–40, approximately 5’8″ (1.73m), with reddish hair and green eyes, weighing between 170–180 lbs. He owned a gold or bronze Pontiac and was allegedly seen with Tina eating ice cream at a cafe around midnight, but he was never identified.
Investigations like this often struggled with limited evidence and uncertain witness accounts, a recurring issue in cases such as The “February Slayings” of Fort Worth, where multiple victims and unclear leads left authorities without definitive answers.
Tina did have two friends with red hair (both now deceased), but those who knew them claim they cared for her deeply—one was a close gay friend who often gave her rides—and it is believed they could not have harmed her.
Furthermore, there is no absolute certainty regarding the witnesses who supposedly saw Tina in that ice cream parlor, as they were not people who knew her well.
Authorities also searched for a blue car seen speeding away from the lake at the time the body was discovered. The brothers of her friend were also scrutinized, as some believed they had followed Tina after she left their house, but no concrete evidence was ever found.

The Horizon Lead
Another lead pointed toward Satanism and an alleged conflict between female groups within the Horizon school: the “White Witches” versus the “Black Witches.” According to recent statements from friends reported on cold case blogs, Tina may have been initiated into esoteric practices by another student as early as late 1972, during her stay at a correctional facility in Winnebago.
Other reports suggest Tina’s interest in the occult actually began when she was briefly detained. During that period, she reportedly shared a cell with a girl named Karla, who introduced her to Ouija boards and spiritualism. It is possible this was the same student she had met in Winnebago.
Some observers viewed the facial disfigurement and the cutting of her hair as signs of a female ritual, especially considering the stab wounds were not inflicted with great force.
A few days after the murder, a Horizon student belonging to the “Black Witches” abruptly left the United States. She returned years later but was never questioned, allegedly because her family had strong ties to the Police Department. Meanwhile, a psychic claimed to have spoken with Tina’s spirit; according to the psychic, Tina confessed she was killed by a “tormented” person whom she did not want to see prosecuted.
Over the years, rumors spread by former Horizon students suggested that Tina had joined one of these groups but then expressed a desire to leave, leading to her being sacrificed as a virgin. However, this theory—which never found factual support—is contradicted by the autopsy, which confirmed Tina was not a virgin (nor had she lost her virginity on the night of the murder).
Legacy and New Hopes
Two similar unsolved murders occurred within a few hundred yards of where Tina was found: a teenager in 1969 (Linda Rice) and an adult woman in 1983. At the site of the discovery, a headstone chosen by her mother still stands, reading: “Tina Marie Davidson, Dead But Not Forgotten.” Notably, in recent years, Tina’s grave in the Racine cemetery has been vandalized multiple times, though it has always been repaired at the city’s expense. Tina’s mother passed away years ago without answers, and her father was never located. Her half-sister Bonnie, who was very close to her, is still alive today. The tragic death of Tina Marie Davidson deeply shook Racine, forever marking the community’s collective memory.
Today, there is renewed hope for a resolution. It recently surfaced (a detail not reported by the press at the time) that Tina’s shirt and jacket—the only items of clothing recovered—were found at the scene. These items have reportedly been sent to a renowned laboratory in hopes of identifying DNA. Bonnie has stated that she has a clear idea of the killer’s identity—someone who is still alive—though she has declined to reveal the name publicly.
