A Westlake Village man convicted of fatally shooting a Pasadena art college instructor at a 2010 party was sentenced last week to 21 years in state prison, the District Attorney’s office said.

A Van Nuys Superior Court jury convicted Steven Ronald Honma, 56, of one count of voluntary manslaughter last November for the killing of Norman Schureman, a 50-year-old Altadena man.

Van Nuys Superior Court Judge Thomas Rubinson imposed Honma’s sentence at a Feb. 2 hearing.

Honma and Schureman were at a Persian New Year’s Eve party in Westlake Village on March 20, 2010, when Honma got into a fight and was asked to leave. Honma left the party but returned with multiple concealed weapons, ammunition and a serrated knife.

When Honma was asked to leave a second time, another fight ensued and Honma drew a handgun, fatally shooting Schureman. The victim was a design teacher at Art Center College of Design in Pasadena.

The case was prosecuted by Deputy District Attorney Maureen Green. The Los Angeles County Sheriff’s Department conducted the investigation.
