YAKIMA, Wash. — Dr. Jay Sloop of Yakima has disappeared in Kiev, Ukraine, where he was on a medical mission, officials with the Seventh-day Adventist Church said Tuesday.

The 77-year-old retired obstetrician was last seen about 6:45 a.m. local time Tuesday after he left a church compound in Kiev for a morning walk, said Jay Wintermeyer, communications director for regional church headquarters in Spokane.

“This is uncharacteristic and unusual,” an emotional-sounding Wintermeyer said 17 hours after Sloop was last seen.

Local police have been contacted and searched his room for possible clues.

According to Wintermeyer, Sloop has been in the Ukrainian capital for three weeks, helping set up a lifestyle center with a team of fellow health professionals.

Wintermeyer said the doctor regularly went for morning walks with other members of the team, but left alone this time after one of his roommates backed out at the last second.

“He was recorded on video security leaving at 6:45,” Wintermeyer said. “I don’t think the security footage showed which way he went.”

Wintermeyer said Sloop had been in Kiev for about three weeks and was scheduled to return to the United States at the end of the week.

“We just hope he’s found safe and sound,” Wintermeyer said.

Sloop is a retired OB/GYN who had a private practice in Yakima from 1969 to 2005, when he was named health director for the Seventh-day Adventist Upper Columbia Conference in Spokane.

Wintermeyer said Sloop continues to live in Yakima, commuting to Spokane as necessary. He is married and has three sons.
