Prosecutors say all six of the youths who conspired to rob a Beersheba Street man in a plot that turned deadly are responsible for his death under the eyes of the law.“In for a penny, in for a pound,” said District Attorney General Lisa Zavogiannis of the six suspects, four of them juveniles, who have been arrested for criminal homicide in the shooting death of Osbaldo Luna, 43.The victim was gunned down Tuesday inside a camper where he lived behind The Detail Shop in Mt. Leo. Investigators suspect Luna may have been asleep when 17-year-old Sam Brinkley charged through the door and opened fire, spraying the inside of the small trailer with at least nine rounds from an SKS assault rifle.Brinkley has reportedly admitted to the killing, telling officers they went there to rob Luna of what they thought was a large amount of marijuana.
