(Vancouver, WA)  --  An investigation is ongoing into a domestic violence shooting at a Vancouver, Washington elementary school that left three people hospitalized including the gunman.  The Clark County Sheriff's office says the shooting happened around 3:15 yesterday afternoon after school had let out at Sarah J. Anderson Elementary School on Northeast 104th Street.  Police say two people were inside a car with two children when the gunman opened fire on them, hitting both adults.  The children were not injured.  Police say the gunman then shot himself following a brief police pursuit.  One of the victims reportedly had a restraining order out against the suspect, who had been released from jail just a few days ago.
