Shawnee ? A northeast Kansas man apparently lived in a shack in a popular park for three weeks while law enforcement, his family and hundreds of friends frantically searched for him.

A park officer found a disoriented and dehydrated Larry Schnackenberg, 58, walking on a trail at Shawnee Mission Park in Johnson County — just over two miles north of where his empty vehicle was found on July 8.

Park officer Rick Reynolds, who has known the Schnackenberg family for years, was on routine patrol Wednesday when he found a shirtless Schnackenberg covered in insect bites on the trail.

“I said, ‘Boy! Larry! This is a good day!'” Reynolds told KMBC-TV. “(He was) real concerned about his family and how they were doing. I told him they were OK and would be a lot better now that they found him.”

Schnackenberg was taken to Shawnee Mission Medical Center, where his family was reunited with him Wednesday evening. The hospital said he was in good condition Thursday.

Schnackenberg told Reynolds he was disappointed that he had missed his daughter’s wedding, which had been scheduled for July 17. The wedding was postponed after he disappeared.

Reynolds said Schnackenberg told him he used plastic bags to stay dry during the heavy rains that fell while he was in the park. But Reynolds got few other details.

“When I found him, I talked about how happy his family was going to be,” he said. “What he was doing and what had transpired for the 20 days he was out here, I don’t know.”

Schnackenberg, a father of five and a retired Hallmark Cards employee, had been the focus of an intense search. Officers, family and friends scoured the large park and Shawnee Mission Lake. Missing person posters were hung across the Kansas City metro area and a Facebook page titled “Looking for Larry” attracted more than 10,500 members.

At this point, it does not appear a crime was committed, said Lenexa police spokesman Officer Dan Friesen.
