A 58-year-old Columbus man convicted of stabbing and assaulting his wife before a standoff with police has been sent to prison. 

Alfredo Santistevan was given six to 12 years in prison for assault and terroristic threats. He'd pleaded no contest after prosecutors amended and dropped other charges. He was sentenced on Friday in Platte County District Court. 

Santistevan was arrested after the standoff on April 3 and taken to a local hospital to be treated for self-inflicted knife wounds. Court documents say Santistevan's wife had a knife wound on her hand and swelling of her nose and around an eye.
