The Kennedy cousin formerly at the center of the notorious case involving the death of Martha Moxley, the daughter of an affluent Connecticut family, has broken his silence to reveal new loose ends and theories regarding the decades-long mystery. 

Michael Skakel, cousin of Robert F. Kennedy Jr., previously spent 11 years behind bars for the 1975 murder of Martha Moxley. In 2013, Skakel walked out of prison as a free man and later saw his conviction vacated in a move that further deepened the mystery of who Moxley’s true killer is. 

In the final episode of statements to police in which he said he spent two-and-a-half hours outside and did not return home until 6 a.m., where he then fell asleep on the sofa in the TV room, the outlet reported. 

Harvey later claimed that John Moxley called him the morning of the teen’s disappearance to help search for her, with the pair searching a pile of brush near the house – a move the Sutton Report reportedly noted was strange. However, the report also pointed out that had the two boys checked the family’s yard, they likely would not have located Martha Moxley’s body. 

John Moxley reportedly said that he only became aware of his sister’s death after his football coach mentioned to him at practice that something happened at his house. 

The Sutton team later determined John Moxley was not the murderer, with Robert F. Kennedy agreeing with investigators in his book, "Framed: Why Michael Skakel Spent Over a Decade in Prison for a Murder He Didn't Commit."

Additionally, the podcast reportedly pointed to the Skakel household’s handyman and gardener, Franz Wittine, as another guest at the home on "Mischief Night." 

Michael Skakel, who was 15 years old at the time of the murder, reportedly revealed Wittine, a regular resident at the house, was the only person who said there were no golf clubs found on the Skakel house lawn, despite others saying there were. In a 1991 interview with investigators, Wittine reportedly said he had no memory of saying that.

Martha Moxley was ultimately found beaten and stabbed to death by a golf club in the yard of her family’s home on "Mischief Night." 

One year after the murder, Wittine reportedly resigned from his position with the Skakel family and later passed a polygraph test in 1991. 

Wittine later died in 1997. 

The podcast went on to point out various loose ends involving the investigation, including the lack of forensic evidence in the case, Connecticut Insider reported.

Swabs taken from Martha Moxley’s groin area in an effort to rule out sexual assault were never introduced as evidence in the trial, and were considered lost under NBC News’ production team reached out to a Connecticut forensics team, which confirmed the evidence remained in state custody. 

The samples were later sent for testing in 2018 and were reportedly determined to only contain Martha Moxley’s DNA.

Additionally, Sissy Ix reportedly recalled a conversation with Rush Skakel Sr., in which he claimed that his son, Michael, allegedly confided in him that he may have killed Martha Moxley. 

However, Michael Skakel was ultimately cleared by Dr. Stanley Lesse after being given sodium pentothal in an attempt to give him mental clarity regarding the situation, with Michael Skakel saying he felt unsure about things after attending the infamous Elan School.

Additionally, a friend of the Skakels reportedly told investigators that both boys were with him at Sursum Corda on Oct. 30, 1975. However, the account directly conflicted with reports that Tommy Skakel had not traveled with his family that evening. 

The series wrapped up with Amanda Knox, an American woman falsely accused of her roommate’s 2007 murder in Italy, weighing in on the mentality of "guilty until proven innocent" in criminal cases, according to Connecticut Insider.

Knox was initially convicted of murder in 2009 and later saw her conviction overturned by an Italian court in 2011. 

Knox reportedly went on to describe how people have told her to "be a little less visible" following her conviction being overturned, and described how the concept of "single victim fallacy" can harm individuals in situations where public perception suggests there is only one victim in a situation.

Michael Skakel’s conviction was ultimately vacated by the Connecticut Supreme Court on May 4, 2018, with prosecutors later deciding to not seek a second trial for Skakel on the murder charge.

With Skakel ultimately being absolved of all charges, the mystery surrounding the decades-old murder of Martha Moxley continues to plague her family and community, with no true promise that the case will ever be solved.
