Marina Elizabeth Habe, a 17-year-old art student and daughter of actress Eloise Hardt and journalist Hans Habe, vanished from West Hollywood in late December 1968 after a date with longtime friend John Hornburg. Her body was discovered days later in a remote ravine off Mulholland Drive on January 1, 1969.
The circumstances of her death remain a mystery, and some investigators have long speculated about possible connections to the notorious Manson Family. Despite investigations by the Los Angeles County Sheriff’s Department into high-profile suspects—including the Manson Family and serial killer John Norman “Co-Ed Killer” Collins—the case remains cold.
Historical Context: A Darker Hollywood
Marina Habe’s disappearance and murder occurred during a turbulent period in California history. The late 1960s were marked by the fading “Summer of Love,” a cultural moment of peace and optimism that was increasingly giving way to violence.
This era also saw the rise of notorious killers, including the Zodiac Killer in Northern California and the Manson Family murders in Los Angeles, situating Marina’s case within a broader pattern of high-profile and shocking crimes.

Timeline and Last Known Movements
On December 29, 1968, at 4:30 p.m., Marina left her mother’s home on Cynthia Street in West Hollywood to meet John Hornburg. That evening, the two attended the Troubadour nightclub on Santa Monica Boulevard, where they joined two other couples: Laurie Kramer and Norm Elder, and Wendy Kleiner and Denis Boses. By 11:30 p.m., Marina and John returned to Hornburg’s home to retrieve her car.
In the early hours of December 30, around 3:15 a.m., Marina reportedly departed Hornburg’s home, heading toward her own residence. Shortly after, at 3:30 a.m., her mother heard cars outside and saw a young man, approximately 20 years old, jump into a black sedan parked next to Marina’s car. The car sped away, and by 3:45 a.m., Marina’s keys were found in the driveway, leading to her official missing-person report.
On January 1, 1969, at 3:50 p.m., her body was discovered in a remote ravine near Mulholland Drive. This sequence of events immediately raised questions for investigators. There was no confirmed eyewitness of Marina being taken, and the scene suggested either a sudden abduction or a carefully staged encounter.
Primary Persons of Interest & Theories
John Hornburg
- Connection: The last known person to see Marina alive.
- The Theory: John Hornburg accompanied Marina to the Troubadour and back to his home, where she undressed and changed from her date outfit into her regular clothes. While he was interviewed extensively as the last witness, police could not link him physically to the crime scene. He moved out of the state after the murder.
John Norman Collins (The Co-Ed Killer)
- Connection: Active serial killer during the late 1960s.
- The Theory: Collins is known primarily for the “Michigan Murders,” but investigators noted striking similarities in the brutality and MO of the Habe case. Collins had visited California, raising questions about his potential involvement. Interestingly, Collins is known as the Co-Ed Killer, and Marina Habe was a Co-Ed, a term that describes an educational setting for both male and female students but is now considered outdated.
Spanky (Unidentified Biker Associate)
- Connection: A figure in the local drug and biker subculture.
- The Theory: A 1988 article in L.A. Magazine revealed that Marina Habe’s stepbrother shared information from a homicide detective working on the case. According to the detective, a drug-dealing outlaw biker known as ‘Spanky’ was considered a potential suspect in the crime.
- Rumors Become Facts: One name that has often been rumored to be “Spanky” is Kirk “Spanky” Smyth. This theory appears to stem from the fact that his name appears in a single 2008 newspaper article—unrelated to the Marina Habe case—and was mentioned in a blog comment that others later repeated until it took on the appearance of fact. However, recently uncovered information confirms that Smyth was not the Spanky involved in the Marina Habe case; it was, in fact, a man with the last name Rothbard.
The Manson Family
- Connection: Proximity and Timing.
- The Theory: The Manson Family was active in the area at the time. Marina lived near the Whisky a Go Go on the Sunset Strip, and several Family members were known to have visited her neighborhood. Tex Watson lived near Marina Habe in early 1968, before he joined the Manson Family. Given the overkill nature of the wounds and the timeline, detectives investigated possible links to Manson followers. Surprisingly, evidence suggests several connections between Marina Habe and the Manson Family. Read more about The Manson Connection →
Investigative Details & Anomalies
The Abduction Site
Marina Habe’s mother heard a male voice and saw a black sedan outside, but she did not witness Marina being taken, nor was there any positive visual identification of her in the driveway or the car. Police noted that the abduction may have occurred elsewhere, and the scene could have been staged, with Marina intercepted and her car later returned. Official reports used qualifiers such as “apparently abducted,” acknowledging the uncertainty. It has never been definitively confirmed that she was abducted from the driveway.
Marina Habe’s Car: The MG Midget
Marina Habe’s red 1968 MG Midget was found with the keys still inside. The handbrake had been pulled completely to its locked position. This was a mechanical feat requiring significant strength due to the car’s cable-driven system. Investigators noted that this made it unlikely Marina had engaged the brake herself, and speculated that a male perpetrator manipulated the vehicle. As reported in the Los Angeles Times on January 2, 1969:
“Miss Habe’s car was parked in the driveway. Officers said the emergency brake was pulled completely up — a position which could not be reached on her car except by exerting great strength. Investigators say that they doubted that the girl was strong enough to pull the brake to that position and speculated that one of her abductors had set the brake lever.”
Forensic Profile
Marina Habe sustained multiple stab wounds, a slashed throat, blunt force trauma, and strangulation. Several of these injuries were independently fatal. The degree of “overkill” suggested a personal motive, such as rage or jealousy, rather than a robbery or random attack. Robbery was ruled out, as her purses—one containing cash and credit cards recovered at the dump site, and a second with money found in her car—remained intact.
Disposal Site & Linked Cases
Marina’s body was left in a remote ravine off Mulholland Drive, hidden from public view and police detection. The concealment suggests the killer had specific knowledge of the area and took time to ensure the body was not easily discovered, unlike random “opportunity” killers of the era.
A similar case involved Rose Tashman, a fellow student at Marina’s former high school who also lived in the same area. She was murdered four months later in 1969, and her body, beaten and strangled, was found just half a mile from Marina’s site, suggesting possible connections in victim profile and geographic pattern.
Another case often mentioned in connection to the Manson Family is Reet Jurvetson, a 19-year-old woman found murdered in November 1969. Her body was also discovered off Mulholland Drive, further highlighting striking similarities in location and timing.
The violent nature of Marina’s injuries and the careful disposal of her body suggested a perpetrator with both knowledge of the area and a personal motive.
Why the Case Remains Unsolved
Decades later, several questions haunt investigators: Who drove the black sedan? Why was the handbrake pulled so tight? The lack of direct eyewitness confirmation and the limited forensic tools of the era made it difficult to determine whether Marina was abducted from her driveway or elsewhere. Investigators could only confirm her disappearance and the discovery of her body, leaving many questions unanswered.
