The Martha Moxley murder case is the 1975 killing of a 15-year-old girl in Greenwich, Connecticut, that went unsolved for 25 years, produced a 2002 murder conviction against neighbor Michael Skakel, saw that conviction vacated in 2018, and ended in 2020 when prosecutors dropped the charges. No one is currently held legally responsible for her death.
The Killing on Mischief Night
Martha Moxley was 15 years old and lived in Belle Haven, a gated community in Greenwich. On the evening of October 30, 1975, the night before Halloween, she went out with friends for “Mischief Night,” a local tradition of ringing doorbells and throwing toilet paper. She spent part of the evening at the home of the Skakel family, neighbors inside the same gated community, and was last seen around 9:30 p.m. near the Skakel property.
She never came home. Her mother searched the neighborhood through the night. The next afternoon, October 31, Martha’s body was found beneath a pine tree in her family’s own backyard. She had been beaten and stabbed. The location, inside a gated neighborhood where a stranger would have stood out, pointed investigators toward someone who lived there or was visiting someone who did.
The Golf Club from Inside the Skakel Home
The weapon was a Toney Penna six-iron golf club. The attacker struck Martha with enough force to break the shaft into four pieces, only three of which were ever recovered. The broken shaft was then driven through her neck.
Investigators traced the club to a set owned by the Skakel family. Rushton Skakel Sr. identified a matching Toney Penna four-iron still in the family’s home, part of a set that had originally belonged to his deceased wife. A neighborhood canvass turned up no other Toney Penna sets in Belle Haven. The weapon had come from inside the Skakel house, and that fact would sit at the center of the case for the next four decades.
The Two Early Suspects Who Were Never Charged
Two people drew immediate scrutiny, and neither was Michael Skakel at first.
Thomas Skakel, Michael’s older brother, was the last person known to have seen Martha alive. He told police he said goodnight to her around 9:30 p.m. at the side of the house and went inside. Years later, he told private investigators a different story: that he had spent roughly thirty more minutes with Martha in what he described as a sexual encounter. That contradiction hung over the investigation for years.
Kenneth Littleton was a live-in tutor who had moved into the Skakel home on the day of the murder. He became a suspect after failing at least two polygraph tests, though those results were questioned because he was described as extremely nervous during testing. He was arrested the following summer on Nantucket for burglary and breaking and entering, and investigators found him erratic and evasive about the night of the killing. Neither Thomas Skakel nor Littleton was ever charged.
How the Case Was Reopened
The case went cold. Greenwich police had never handled a murder investigation of this complexity, and the case sat without an arrest into the late 1980s.
In 1992, a Skakel family attorney hired Sutton Associates, a Long Island private investigative firm, to conduct its own reinvestigation. The firm reportedly spent several years and more than a million dollars reinterviewing witnesses. The resulting Sutton Report was never meant to be public, but portions leaked. It disclosed that both Thomas and Michael Skakel had lied to authorities about the night of October 30, 1975, and that Michael had reportedly confessed to the murder during a therapy session at the Elan School, a residential treatment center in Maine, before recanting.
In 1998, former Los Angeles detective Mark Fuhrman published a book examining the case and pointing toward Michael Skakel. The public pressure that followed pushed Connecticut authorities to convene a one-judge grand jury, and that proceeding led to charges.
Michael Skakel’s Arrest and 2002 Conviction
Michael Skakel was arrested on a murder warrant on January 19, 2000. He had been 15 at the time of the killing, and a Connecticut court ordered his case transferred to the regular adult criminal docket. He was tried in 2002.
Skakel was a nephew of Ethel Skakel Kennedy, the widow of Robert F. Kennedy, which guaranteed heavy media coverage. The prosecution’s case was entirely circumstantial. There was no DNA evidence, no eyewitness to the killing, and no confession that held up under scrutiny. Prosecutors relied on former classmates from the Elan School who testified that Skakel had made incriminating statements in the years after the murder. They also pointed to the golf club’s origin inside the Skakel home, Skakel’s movements that night, and what they characterized as jealousy over Martha’s attention to his brother Thomas.
The jury deliberated for four days and returned a guilty verdict. The judge sentenced Skakel to 20 years to life. Twenty-seven years had passed since the night of the murder.
Why the Conviction Was Overturned
The conviction did not hold. Skakel’s post-conviction lawyers argued that his trial attorney, Mickey Sherman, had provided constitutionally inadequate representation. In 2013, Judge Thomas Bishop, presiding over Skakel’s habeas corpus petition, agreed and ordered a new trial. Skakel was released on bail.
The case moved through the Connecticut Supreme Court, and in 2018 that court vacated Skakel’s conviction. The decisive issue was a single witness Sherman never called: Dennis Ossorio, the former boyfriend of Skakel’s cousin Georgeann Dowdle.
Skakel had claimed that on the night of the murder he left Belle Haven and went to the home of a friend named Terrien, miles from the crime scene. Several Skakel family members testified to this at trial, and the prosecution attacked their accounts as a family conspiracy to protect Michael. Ossorio was not a Skakel. He had no stake in the outcome, could have independently placed Michael at the Terrien home during the likely time of the murder, and lived nearby throughout the trial. Sherman never contacted him.
The court held that Sherman’s failure met the two-part test for ineffective assistance of counsel under Strickland v. Washington: his performance was objectively deficient, and there was a reasonable probability that competent representation would have produced a different verdict. Without Ossorio, the jury never heard from an independent witness placing Skakel away from the scene.
Why the Charges Were Dropped in 2020
With the conviction vacated, the state could have retried Skakel. In 2020, prosecutors announced they would not. The murder charge was dropped through a nolle prosequi filing. Prosecutors concluded that proving the case beyond a reasonable doubt was no longer feasible: key witnesses had died or become unavailable, memories had faded across more than four decades, and the circumstantial case that had barely held together the first time would be harder to reassemble.
A nolle prosequi is not an acquittal and not a dismissal with prejudice. It means the state has chosen to abandon the prosecution, without permanently barring future charges. Connecticut has no statute of limitations for murder, so in theory the state could refile if new evidence emerged. In practice, the Moxley case is closed without a conviction, and no one stands legally responsible for the killing.
