ORLANDO, Fla. -- A 72-year-old Kansas minister with medical problems is recovering in a hospital Friday after he was apparently left sitting in a wheelchair on a curb outside Orlando International Airport for three days.

Kenneth Davis was reported missing this week when family members in Wichita lost contact with him after an AirTran flight to Orlando. Davis was scheduled to attend a Florida gospel conference this week, the family said.

Family members told WKMG-TV that Davis was not feeling well and called for assistance at the airport.

Davis' daughter, Melinda, said her father was then put in a wheelchair and rolled to a curb outside Orlando International Airport, where he sat from midnight Monday until Wednesday afternoon. Orlando police found Davis sitting in the wheelchair Thursday.

"He urinated on himself and his clothes were soiled but he was dressed in nice clothes -- didn't look bummy or anything like that," daughter Melinda Davis said.

"And nobody noticed him?" Local 6's Erik von Ancken asked.

"No one noticed," Davis said. "(He was found) curbside of the sidewalk where you catch a taxi where people walk by. Several people walked by."

The family said Davis suffered a stroke during the days sitting outside the airport.

"He is alive but unfortunately he did suffer a stroke and we feel like it contributed a lot to him being in the heat," son Kenneth Davis said.

A spokesman for the airport said he could not be certain that Davis sat in the same spot for such a long time and said "it doesn't seem plausible," von Ancken reported.

Davis remains in an Orlando hospital and is barely able to speak, the report said.

The family is asking for surveillance video to determine how long Davis was sitting outside the facility.

The incident is under investigation.
