LE MARS, Iowa (KTIV) - A Northwest Iowa man convicted in the 2016 death of his sister has been denied a request to further review his case by the Iowa Supreme Court.
Thomas Bibler was convicted in January 2019 on second-degree murder in the stabbing death of his sister Shannon Bogh. He was sentenced a month later to serve 50 years in prison but would be eligible for parole in 35.
Bibler filed an appeal in the case, claiming he should be acquitted because he was involuntarily intoxicated at the time of the stabbing.
Bibler claims he had Zolpidem, a generic form of Ambien, along with Lithium in his system at the time of the incident. In their ruling, the Iowa Supreme Court wrote "While common law previously recognized a distinction between voluntary and involuntary intoxication, our legislature codified the intoxication defense in 1979 and eliminated any distinction."
Bibler was initially charged with first-degree murder, following a standoff with police at his Le Mars apartment in June of 2016.
Bogh died of stab wounds at the hospital in Le Mars.
