In a development that rekindles interest in a long-standing mystery, Michael Skakel, a member of the prominent Kennedy family, has chosen to speak out about the infamous case surrounding the death of Martha Moxley. Moxley was a young girl from a wealthy Connecticut family whose murder in 1975 has baffled investigators for decades.

Michael Skakel, a cousin of Robert F. Kennedy Jr., was previously convicted for the murder of Moxley, serving 11 years in prison. However, his conviction was overturned in 2013, leaving the true identity of Moxley’s killer shrouded in mystery. This turn of events only deepened the enigma surrounding the tragedy.

The case has recently been revisited in the final installment of NBC News’ podcast series, “Dead Certain: The Martha Moxley Murder.” The podcast explores various possible suspects and new pieces of evidence, yet several unresolved aspects of the case continue to linger, as reported by Connecticut Insider.

Skakel expressed his thoughts on the podcast, reflecting on the impact the case has had on his life. “Being Michael Skakel has been both a blessing and a curse. I’ve encountered some truly remarkable people,” he shared. “Yet, the trial and its aftermath have defined me in the eyes of the public, who only know the narrative presented by their television screens. Much of it, unfortunately, has been blatant falsehoods.”

The podcast episode also brought attention to a significant piece of evidence—a stain discovered in the Moxley family’s TV room by their maid, Theresa Tirado, just a day after the 15-year-old was brutally killed outside her Greenwich home on October 30, 1975.

In Tirado’s account to police at the time, she noticed that Martha Moxley’s brother John’s bed was empty, and his door was open the morning of the murder, but had not yet been told the teenager was missing. At 9 a.m., Tirado reportedly heard a loud crash in the house and witnessed John Moxley and a friend, John Havey, watching television about 15 minutes later. 

At around 11 a.m., Tirado told investigators that the two boys went outside right around the same time she heard another loud crash inside the house. The pair then returned to the house briefly before leaving, Connecticut Insider reported. 

When Tirado later went into the TV room, she noticed smear marks that were believed to be blood. However, she reportedly wiped up the marks, not realizing what it potentially was.

John Moxley later corroborated Tirado’s account regarding his and Harvey’s whereabouts, though he told investigators he did not hear any crashes coming from inside the house, the outlet reported. He went on to suggest the smear marks could have been a food stain. 

However, the potential blood stain was reportedly included in a pretrial memo by attorney Linda Kenney Baden, but was never looked into by Skakel’s attorney, Mickey Sherman. 

The podcast also noted that Tirado died in 2012. 

Additionally, the outlet reported that John Moxley was the fourth individual noted in the Sutton Report in the 1990s, with investigators noting that “a few unresolved points still demand clarification and examination.”

Initially, Michael Skakel, Tommy Skakel and tutor Ken Littleton were profiled in the report regarding Moxley’s murder. 

One of the points of note regarding John Moxley was reportedly his statements that he returned home around 11 p.m. on Oct. 30, and was awoken by his mother at 3:30 a.m. the next morning to help look for his missing sister. 

In 2002, John Moxley went on to testify that he only spent about 15 minutes searching for Martha Moxley, which contradicted his 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.
