A Topeka man will be sentenced May 11 after being found guilty of killing his mother at a home they shared in 2011.

A Shawnee County jury on Tuesday found 40-year-old Jason Hachmeister guilty of the premeditated murder in the death of Sheila Hachmeister. Prosecutors say the victim was stabbed several times and strangled.

Testimony during the trial indicated that Jason Hachmeister would receive a $125,000 life insurance payout because of his 58-year-old mother’s death.

The defense had contended a man Sheila Hachmeister met on an online dating service killed her.

Prosecutors say they will seek a “Hard 50” sentence for Hachmeister.
