PINEVILLE, Mo. — A Joplin man has entered a plea of guilty in Newton County Circuit Court to the 2019 murder of his son’s longtime girlfriend.

“This plea will offer closure and some amount of justice to the family of Sarah Tyminski,” said Newton County Prosecuting Attorney William Lynch. “The decision to proceed as we have is not one I take lightly. After full discovery was completed in this case, considering the availability of some witnesses and the risk associated with a jury trial, this is a just and certain outcome.” Lynch stated that the defendant taking responsibility for his actions and the plea limiting the scope of the defendant’s appeals were important factors in his decision.

A sentencing hearing is set for June 17, 2021. At that hearing, the state and defense will have the opportunity to make argument as to what sentence the defendant should receive. The range of sentencing for the A felony of Murder in the Second Degree is 10 to 30 years, or life, in the Missouri Department of Corrections. No plea agreement was made limiting the range of punishment the judge can consider.

The case was investigated by the Newton County Sheriff’s Office and prosecuted by William Lynch, J.D. Hatcher, and Sarah Crites, of the Newton County Prosecutor’s Office. Newton County Prosecutor’s Office Media Release.
