A preliminary hearing has been scheduled for a man charged with conspiracy to commit murder in Leavenworth. The hearing for Jeffery M. Samulczyk is scheduled for Feb. 24 in Leavenworth County District Court. The date for the hearing was selected Friday as Samulczyk appeared in the court. Samulczyk, 37, is charged with conspiracy to commit first-degree murder and interference with law enforcement. The charges are connected to the stabbing death of Joshua Gilson, who was found dead Oct. 30 at his Leavenworth home. Gilson’s wife, Alexandra, faces a charge for allegedly killing her husband. Evidence will be presented during the Feb. 24 preliminary hearing, and a judge will determine if there is sufficient evidence for the case against Samulczyk to go forward.
