From JB Herren at Old School Gun School:

Reliable information can be difficult to find.  Here is an update on the November 26^th shooting outside an elementary school in Vancouver, WA.

A husband and father, with a history of domestic violence, shot his estranged wife and her mother as they sat parked outside a Vancouver, WA elementary school, after loading their three children into the car.  The wife was pronounced dead, and her mother was shot three times, but is expected to recover.  All three children witnessed the shooting.  The children were not physically injured.
