SUNDAY, VISITACION VALLEY: A little before 8:30 p.m., near the intersection of Sunnydale Avenue and Sawyer Street, an unidentified man was shot and killed. No arrests have been made. If SF Crime's statisitcs are accurate, this brings the murder rate in SF to 99. One more to go, folks. (SFGate)

SATURDAY, CALDECOTT TUNNEL: Elnora Caldwell, 46, was stabbed to death by her ex-boyfriend inside his pickup truck, then "pushed her out on a road just off Highway 24 near the Orinda side of the Caldecott Tunnel in front of stunned motorists." Robert Woods, 47, was arrested for her murder. Not that every murder isn't jarring, but SFGate has the graphic and sad tale of what went down, right here.
