In one interview Viens said that he and his wife had argued after he accused her of stealing money from their restaurant.
In a later interview, he said that the couple had taken cocaine, and in yet another interview he said she was bothering him while he was trying to sleep.
Viens told police that he had previously taped her up to prevent her from "driving around wasted, whacked out on coke and drinking."
"For some reason I just got violent," Veins said.
