Richard Graf Barrett, 29, was shot and killed outside the Fuse bar in San Francisco’s North Beach neighborhood on November 25, 2008. When he resisted and tried to flee, he was shot twice in the back, collapsed, and died inside the bar.

The investigation led to the arrest of Charles Cheese Heard, 26, who was taken into custody in July 2009 while on parole. Prosecutors said Heard had a pattern of stealing expensive jewelry and accused him of participating in the attempted robbery that ended with Barrett’s death. During the trial, jurors received conflicting evidence about whether Heard personally fired the shots; the jury nonetheless convicted him of first-degree murder and attempted robbery under the felony-murder rule.

Barrett is survived by his mother Laura Barrett and his young daughter Giselle, who attended the sentencing hearing and spoke about their loss. Does anyone have information about Barrett’s last night or the necklace that could shed more light on what happened?
