Dr Richard Warn was shot to death at home by his two adult sons, Michael and Mark, who did not live there at 2483 Brentwood Rd, Beachwood Ohio. Police had to force open the door after a call from Dr Warn’s wife, who was returning from a trip and had no keys. The police tracked the sons to the home their father had purchased for them at 4362 Elmwood Ave. in South Euclid. A SWAT team was finally able to gain entry, finding the sons dead in a double suicide. Testimony supports the fact that the sons were mentally ill.
