(AP Photo/Ed Andrieski) (User Submitted) – The 29-year-old Australian twins shot at a firing range in Colorado meant to kill each other in a suicide pact, sheriff's officials said. Witnesses say the twins were shooting and chatting for about 90 minutes when they suddenly fell to the floor of the booth they occupied. Both had gunshot wounds to the head. One died, and the other is hospitalized but was able to speak with authorities today. "Based on the physical evidence collected, the surviving sister's statements, and video surveillance footage from the shooting center, the Arapahoe County Sheriff's Office believes that this incident was indeed a suicide and attempted suicide," said a statement.
