This article contains plot spoilers for the 2017 series of Twin Peaks.
Ike "The Spike" Stadtler was a hitman hired by Duncan Todd.
Stadtler was at a motel recording dice rolls when he received a contract from Duncan Todd, in the form of an envelope containing photographs of Lorraine and Dougie Jones. He visited Lorraine's place of work and stabbed her to death with an awl, also killing two of her coworkers in the process. Afterward, Stadtler was visibly upset to realize that the awl had been damaged during the assault.
Later, when Janey-E Jones and Dale Cooper, who was thought to be Dougie at the time, exited the building in which Dougie worked, Stadtler ran through the crowd of people towards the couple. When he got to them, Cooper was immediately able to disarm him, with some help from Janey-E. The arm appeared to Cooper in miniature form, screaming at him to squeeze Stadler's hand off. Unable to take anymore of Cooper's hits, Stadtler fled from the scene. Authorities later came to take statements and investigate the crime scene, and collected a chunk of flesh from Stadtler's hand which had adhered to the handgun.
After this failure, Ike left a message for "J.T." saying "no cigar" and that he was taking medical leave. As he left his motel room with his hand in a cast, he was cornered in the hallway and arrested by Detectives Fusco for attempted murder.
