According to witnesses, a dispute erupted at a weekend party between Schureman and another individual, Steven Honma. When the argument grew heated, Honma, described by witnesses as an Asian-American male, left the scene and allegedly returned with a handgun, and fatally shot Schureman in the torso.
According to LAPD, Honma, 46, is now in custody.
Schureman taught sketching and product design at the prestigious Pasadena art school for more than 20 years.
