 A romantically related domestic incident is believed to have been the root cause of what seems to have been a murder-suicide last Thursday in North Liberty. Police responded to Stewart Street in North Liberty on a report of a double shooting. The 911 caller said her husband had shot her friend and then turned the gun on himself. 51-year-old David Dewey was dead from multiple gunshots when the police arrived, and officers also discovered 53-year-old Robert Carter, who appeared to have turned the gun on himself.
