The preliminary report from an autopsy on Wednesday indicated that the patient, 47-year-old William Roebling, suffered from coronary artery disease and had an enlarged heart, Stuart said.
Stuart said that when Roebling played a prank on one of his roommates around 5 p.m. Monday, the male roommate hit Roebling's buttocks with a rolled-up magazine. Roebling then punched the roommate in the face, Stuart said.
The altercation spilled out into a hallway near a nurses' station, where a third patient got between the two men, Stuart said.
When Roebling again tried to get at his roommate, hospital staff intervened and put Roebling face-down on the floor, Stuart said.
The staff members placed Roebling's wrists in soft, Velcro restraints and rolled him onto his back, Stuart said.
They then noticed that Roebling was turning blue and was having trouble breathing, Stuart said. Staff started CPR, but Roebling stopped breathing and was pronounced dead at 5:43 p.m., Stuart said.
Roebling's roommate suffered a spilt lip during the altercation, Stuart said.
