Anthony Smith walked up to 34-year-old Andre Qualls' car, reached through the window, and stabbed him once through the heart, later explaining that "something took control of me," according to police testimony.
After the 29-year-old San Leandro man was shot and killed, police learned of two other surviving shooting victims believed to be linked to the same incident.
The gun used to kill an Oakland man was found during an Aug. 16 police raid, and 12 hours later a woman who'd allegedly talked about her involvement in the homicide was gunned down in the hills.
