A community is horrified when seven trick-or-treaters in Pasadena, California are sprayed with gunfire on Halloween night in 1993, leaving three young boys dead. Investigators rely on forensic clues, eyewitness accounts, and street informants to find the killers, three gang members bent on avenging a friend’s death. Los Angeles County Deputy District Attorney Antony Myers leads the prosecution and paints a picture of that harrowing night; a picture that he hopes will lead the jury to decide that the defendants are guilty of capital murder.
