On Valentine’s Day 2016, 28-year-old Jerrid Goodpaster was fatally shot outside a Starbucks at Keizer Station in Keizer, Oregon following a confrontation that stemmed from a planned robbery. Authorities say the motive was a robbery involving marijuana, not a random attack, and the encounter ended with Goodpaster’s death.

Investigators identified 25-year-old Timothy Bernard Calloway of Salem as a suspect. He was arrested by the Eugene Police Department and charged with murder, first-degree robbery, and unlawful use of a weapon. Calloway was tried and in June 2017 found guilty on all counts; he was later sentenced to life in prison. Goodpaster’s wife of nearly a decade, Angela, was present during the sentencing when Calloway offered an apology to the family.
