Moon-area pediatrician found in country club lake died of natural causes – Tribune-Review

Former colleagues of Dr. In O. Ryoo remembered the pediatrician as a kind, well-liked doctor, a day after his body was found in a golf course lake.

“Doctor Ryoo was a wonderful physician,� said Megan Eaton, a spokeswoman for Ohio Valley Hospital, where Ryoo worked for 38 years. “We were privileged to have him on our staff for so many years and are very sorry to hear of his passing.�

Ryoo, 73, of Moon was identified Friday by Moon police. He was found Thursday in the water at Montour Heights Country Club, where he played golf frequently, police said.

The Allegheny County Medical Examiner’s Office said Ryoo died of natural causes. A spokesman at the office said he had atherosclerosis, a disease in which plaque builds up in the heart’s arteries. The office reported he likely died of a heart attack and fell into the lake.

Ryoo was a pediatrician at Ohio Valley from 1975 to 2013, when he retired, Eaton said. He still had office addresses in Kennedy and Coraopolis. No one answered phones at either location Friday. Family members could not be reached.

Dr. Gary Sauer, who has a family practice in McKees Rocks, was on staff with Ryoo at Ohio Valley and saw several of Ryoo’s former patients once they graduated from pediatric care.

“I also got the sense that he was quite beloved and well respected with his patients,� Sauer said.

Other colleagues said they had positive experiences with him, Sauer said.

“He was well respected by the other physicians and OBGYNs here,� he said.

Ryoo was a member of the Pennsylvania and national chapters of the American Association of Pediatrics. Ryoo had an active surgical and medical physician license, according to the Pennsylvania Department of State.

Moon police responded to a call Thursday afternoon about an empty golf cart parked near the edge of the lake, said township police Chief Leo McCarthy.

Club officials told police Ryoo teed off at 2 p.m. Thursday and regularly played alone. A spokeswoman at the club could not confirm whether Ryoo was a member there.

Officers arrived to find the cart with golf clubs with Ryoo’s name on them, car keys and a cellphone. Officers saw a hat floating on the lake, McCarthy said.

The department summoned divers from Crescent Township Fire Company. His body was found 10 to 15 feet from the edge of the lake in seven feet of water, McCarthy said.

“He’s very, very well known in the community,� McCarthy said. “People are very upset about it.�
