Gun rampage as son briefed in hospital

Baltimore police Commissioner Frederick H Bealefeld III said the doctor had been talking to 50-year-old Warren Davis yesterday morning when he “became emotionally distraught and reacted ... and was overwhelmed by the news of his mother’s condition”.

Mr Bealefeld said he did not know what the woman was being treated for at Johns Hopkins Hospital, known for its cancer research and treatment.

Davis then pulled a semi-automatic handgun from his waistband and shot the doctor once in the stomach, the commissioner said.

The doctor collapsed outside room 873 of the Nelson building, where Davis’s mother, Jean, was being treated.

Davis then holed himself up inside his mother’s room for more than two hours during a stand-off with authorities.

When officers made their way to the eighth-floor room, they found Davis dead on the floor and his mother dead in her hospital bed. The doctor who was wounded, Dr David B Cohen, was expected to survive.
