From Gazette website: “Autopsies are scheduled Monday for two people slain in Friday’s deadly rampage at Planned Parenthood in west Colorado Springs, one of many grim steps ahead as the city continues its recovery after a gunman’s five-hour reign of violence.
Until the tests are completed and family members are fully notified, names of the two civilian victims are being withheld, said El Paso County spokeswoman Jacqueline Kirby.”
