Massachusetts Doctor Found Guilty of Voluntary Manslaughter in Wife's 2020 Death
Ingolf Tuerk was found guilty of voluntary manslaughter for the 2020 death of his wife, Kathleen McLean, instead of first-degree murder.

A doctor residing in Dover, Massachusetts, has been found guilty of voluntary manslaughter in the case of his wife’s death that occurred five years ago. The defendant, Ingolf Tuerk, faced accusations of first-degree murder in the 2020 death of Kathleen McLean, with allegations of strangulation and body disposal in a pond. However, after deliberation, the jury convicted him of the lesser charge of voluntary manslaughter in the first degree. Sentencing is scheduled for May 16, resulting in disappointment for the victim’s family.
Massachusetts doctor found guilty of voluntary manslaughter
The trial, which commenced on March 27 in Norfolk Superior Court, concluded with the jury's conviction of Ingolf Tuerk for the lesser charge of voluntary manslaughter in the first degree. The defense argued that the killing was not premeditated, claiming the events were a result of Kathleen McLean’s purported plan to gain control of Tuerk’s finances. In stark contrast, the prosecution depicted a calculated and cold-blooded act committed by Tuerk who disposed of McLean’s body in a pond, likening it to discarding a piece of trash.
Disappointment in Justice
Richard McLean, brother of the victim, expressed disappointment with the verdict, stating, “Essentially, he’s walking out scot-free. It’s a shame the whole thing took five years for us to get to this point, to walk away extremely disappointed.” He emphasized the perceived injustice, indicating that Tuerk had evaded accountability for the murder of his sister.
The Defense's Argument
The defense attorney, Kevin Reddington, contended that the killing was not premeditated and characterized it as an act of self-defense. He accused the victim of orchestrating a plan to gain control over Tuerk’s financial assets, arguing that Tuerk acted in a state of intoxication, devoid of intent to kill. In response, the prosecution countered these claims, asserting that Tuerk's actions were deliberate and motivated by financial concerns.
The Prosecution's Perspective
Assistant Norfolk District Attorney Lisa Beatty painted a different picture, arguing that Tuerk’s behavior exhibited calculation and composure rather than rashness or self-defense. She refuted the defense's narrative, asserting that Tuerk's actions were driven by a motive to kill rather than an instinctual act of preservation. The prosecutor emphasized Tuerk's lack of attempts to resuscitate McLean or alert emergency services after the incident, furthering the notion that the act was premeditated.
During the trial, Ingolf Tuerk testified about his marriage to Kathleen McLean, which was facilitated through an online dating app and conducted in Las Vegas. He recounted his level of intoxication during the wedding, expressing a lack of memory of the event. Subsequently, he narrated the events leading to McLean’s death, alleging that she attacked him with a glass, prompting his fatal response. Despite denying premeditation, Tuerk admitted to police his involvement in disposing of McLean’s body in a pond.
