The Shocking Murder of Christa Helm: A Hollywood Starlet's Tragic Demise

In the glamorous world of 1970s Hollywood, beauty and talent reigned supreme. But behind the glitz and glamour lay a darker reality - one that would ultimately claim the life of stunning actress Christa Helm. On February 12, 1977, this ravishing 27-year-old was brutally murdered on a quiet West Hollywood street, her body discovered in a pool of blood outside 9022 Lloyd Place.

A Life Cut Short

Christa Helm, born Sandra Lynn Wohlfeil, had it all - stunning looks, a captivating personality, and a fierce determination to make it big in Tinseltown. But beneath the surface lay a complex web of relationships, rivalries, and secrets that would ultimately prove fatal.

The B-list movie starlet's life was a whirlwind of parties, romances, and high-profile connections. She had a knack for courting the press, but her murder barely made a ripple in the celebrity-studded waters of 1970s Hollywood. It wasn't until true crime writer Jamey DuVall delved into the case that the full extent of Helm's tragic fate began to unfold.

A Killer in the Shadows

True crime writer and podcast host Jamey DuVall has been investigating the case for a decade, and exclusively revealed his discoveries to the Daily Mail

As DuVall dug deeper into the case, he uncovered a chilling pattern of events that suggested the killer was someone who knew Helm intimately. "There's no way this killer did not know Christa," he said in an exclusive interview with The Scholarly Note. "It wasn't a simple mugging; they wanted to defile her, mutilate her, destroy her beauty."

The attack was brutal and calculated, with 22 stab wounds inflicted by a butcher knife, followed by blows from a blunt object. Christa's body lay face down in the blood-soaked street, her hand clutched between her thighs as if trying to protect herself. Her Tommy Boy purse, rumored to contain incriminating secrets about her high-profile relationships, was missing, fueling speculation about what Helm might have known.

A Life of Secrets and Scandals

Helm's diary, a salacious record of her alleged conquests with A-list celebrities like Warren Beatty, Jack Nicholson, Mick Jagger, Joe Namath, and Johnny Rivers, had been rumored to contain explosive secrets. Her audio tapes of reported flings only added fuel to the fire. But Helm was no one-trick pony; she was a multifaceted individual with her own agenda.

The actress's personal life was a tangled web of relationships - including a romance with financier Bernie Cornfeld and his alleged procurer, David Stein. Stein, once dubbed "the second greatest pimp in NYC," was accused of using women to dig up information on wealthy clients. DuVall believes Helm may have stumbled upon some unsavory dealings.

A Trail of Clues

Amid salacious revelations about the mother-of-one's personal life, including that she kept a sex diary chronicling escapades with celebrities and politicians, combined with a laundry list of persons of interest - the case bamboozled police and went cold. (Helm pictured in 1975)

As investigators re-examined the case, a few key details emerged that hinted at a larger conspiracy. Christa's clipped fingernails had been preserved with tissue underneath them, yielding an astonishing DNA result: that of an unidentified female. This revelation sparked hopes that the killer might be caught through DNA matching.

But as DuVall's investigation deepened, it became clear that the case was far more complex than initially thought. The disappearance of Christa's lover, Patti Collins, in the aftermath of the murder raised questions about their relationship and potential motives.

The Suspects

Limo driver Thurman Brooms found the Starsky & Hutch actress' mangled body around 1:30am and claimed to have seen her take her final breath. A bloodsoaked Helm was laid on her left side with her hand gripped between her thighs, her legs partially under the car (pictured)

Over the years, several individuals have been fingered as possible suspects, but none have ever been charged. Among them is David Stein, who died in 2021 without ever being questioned further. Rudy Mazella, a known associate of Stein's, was also investigated but denied any involvement before passing away.

One intriguing lead points to Lionel Ray Williams, convicted of murdering Rebel Without a Cause icon Sal Mineo the year before Helm's death. Detectives initially linked the two cases, but this theory allowed the true killer to slip through their fingers.

A Legacy of Secrets

Police at the time said they believed Helm was murdered because she 'knew too much about some important people' and 'there is the possibility that [Christa's] diary could have been taken for its blackmail potential'

Christa Helm's murder left behind a legacy of secrets and unanswered questions. Her daughter, Nicole, has spent her life searching for answers about her mother's tragic fate. "Her daughter has a right to know who did this to her mother," DuVall said, emphasizing the importance of justice.

The Final Reveal

DuVall is determined to uncover the truth behind Christa Helm's murder, convinced that "the answer is right there, one conversation away, one lead away." Will justice finally be served for this beautiful and troubled starlet? Only time will tell.

Christa had a turbulent early life. Born Sandra Lynn Wohlfeil, her parents divorced when she was a young child

Helm became pregnant at 17 by a 34-year-old karate school teacher and married him. A day after the ceremony, he left and never saw her again or met their daughter Nicole. (Nicole is pictured above with her sons)

The 1977 detectives initially linked the murder to the stabbing of Rebel Without a Cause icon Sal Mineo (left with James Dean in 1955), which took place in the same neighborhood exactly one year earlier - and DuVall believes this focus allowed the real killer to slip away

Christa was linked to actor Michael Sarrazin. (Sarrazin pictured in The Sweet Ride in 1968 with Jacqueline Bisset)

After welcoming her daughter Helm moved to NYC to pursue modeling and acting - she planned to reunite with her daughter full time when she was 10. (Helm pictured in the 1970s with close friend and costume designer Lennie Barrin)

Christa's love diary reportedly included entries ranking lovers including Mick Jagger (pictured 1970 with Anita Pallenberg)

She was also linked to quarterback Joe Namath (pictured in 1974)

Helm's lover Patti Collins (pictured with Helm) vanished in the aftermath of the murder and has never been located. It is unclear if she was ever interviewed

David Stein, also known as David Marcus, has emerged as the person DuVall has focused on the most. Stein (pictured) - who had previously been arrested for imprisoning and assaulting a Playboy playmate in 1972 - crossed paths with Helm in LA

Helm had a part in 1972's The Legacy of Satan

Sopranos star Tony Sirico (left) was also drawn into the investigation amid rumors he had taken 'furs and tapes' from Helm's apartment on the night of her murder. Sirico - who died in 2022 - denied even knowing Helm

Known drug dealer Rudy Mazella (pictured) allegedly confessed to murdering Christa - but later denied ever making the revelation

DuVall is compelling police for access to both the original police reports and 2006 cold case files which he believes hold a wealth of untapped evidence - including the whereabouts of the blue jumpsuit Helm was murdered in. (Helm pictured in Wonder Woman in 1976)
