A 55-year-old man from Fenton, Michigan, was recently convicted on multiple charges for an attack on his ex-fiancée that took place nearly five years ago. John Frederick Siemen was found guilty of assault with intent to murder, assault with intent to do great bodily harm less than murder by strangulation, domestic violence, and felony firearm, according to CBS News Detroit.

In August 2020, police responded to a domestic disturbance in Fenton. They found Siemen applying pressure with a towel to the head of a woman who had been shot in the face, resulting in the loss of her eye. Siemen said the injury happened during a struggle over a gun when his then-fiancée attempted suicide. However, evidence from the investigation did not support this claim. Genesee County Prosecutor David Leyton stated, "These types of cases are never clearcut and I want to commend the City of Fenton Police for their unwavering commitment to uncovering the truth of what actually occurred and to assistant prosecutors Sara Brady and Ezekiel Zanetta and support staff for their steadfast efforts in seeking legal justice for the victim," as reported by WNEM.

Siemen has been convicted of assault and strangulation of his ex-fiancée and is scheduled for sentencing on April 15, with a possible life sentence. The victim was treated at Hurley Medical Center and later transferred to the University of Michigan Hospital in Ann Arbor. Her testimony about past domestic issues was supported by physical evidence. Prosecutor Leyton stated, "This is a very sad and tragic set of circumstances that has fractured the lives of many and none more so than the victim herself," as stated by Mid Michigan Now. Leyton's office acknowledged the efforts of law enforcement and assistant prosecutors Sara Brady and Ezekiel Zanetta.
