Thomas Markle Sr., 82, may be unable to face trial on child pornography allegations if a reported dementia diagnosis renders him incompetent to understand proceedings or assist in his defense, according to legal and medical experts. The estranged father of Meghan Markle has been under investigation in the Philippines for alleged possession of child sexual abuse material.
While a dementia diagnosis alone does not automatically prevent an arrest, it could become highly relevant in court, experts told Page Six. "A dementia diagnosis doesn’t automatically prevent an arrest if investigators have probable cause," stated former FBI agent Jason Pack. "It could become relevant in court, but those are separate questions: whether someone can understand the charges and help with their defense, and whether they were legally responsible at the time of the alleged conduct."
Neurologists note that dementia can affect a person's ability to make decisions. "There could be a problem with the idea that he would lack capacity or the capability of making his own decisions, and how that plays into being able to prosecute someone," said Dr. Jeremy M. Liff, a board-certified neurologist. He described it as similar to an insanity plea, but with a diagnosed neurological disorder impacting competency.
Dementia, particularly frontal lobe degeneration, can lead to reduced inhibitions, potentially manifesting in behaviors like shoplifting or increased suspicion, Liff explained. However, he cautioned that such a diagnosis might not excuse specific actions.
"In the case of child pornography, certainly if you could demonstrate that someone who was accused was able to carry out the steps that it takes to obtain child pornography or to distribute it, then that goes against their dementia defense because they were able to carry out those other tasks," Liff said. "I think something that specific is not something that you could typically blame dementia on, but of course, it’s a case-by-case basis."
Forensic psychiatrist Dr. Carole Lieberman indicated that if Markle were charged, his legal team would likely present medical experts to assess his condition. This evaluation could involve reviewing medical records, psychological testing for competency, psychiatric examinations, and neurological testing. If found incompetent, efforts might be made to restore competency, though Lieberman noted that most dementia cases are irreversible.
Should competency not be restored, charges could be dismissed, or Markle might be placed in an appropriate care facility. However, she stressed that this outcome is not guaranteed, and incompetence does not always preclude legal consequences.
Thomas Markle Jr. reportedly alerted authorities to the alleged child pornography material found among his father's belongings in the Philippines. The FBI has acknowledged awareness of the allegations and stated it would support Philippine authorities as appropriate. Thomas Markle Sr. has denied the accusations, calling them "sick lies."
Meghan Markle previously stated she was "deeply distressed" by the allegations and that keeping her children away from their grandfather was for their protection. No criminal charges have been formally announced against Thomas Markle Sr. in relation to the investigation.
