Doran Lee Van Winkle, 53, disappeared from his Tulsa, Oklahoma, home in 2007. He was described as a white male about 5 feet 10 inches to 5 feet 11 inches tall, weighing 140 to 145 pounds, with brown hair and brown eyes.

His house was found abandoned and investigators noted that essential medical equipment required for his daily treatment remained behind. Relatives stressed that Van Winkle had serious health conditions and could not have remained well without that equipment. Neighbors said he sometimes took long walks, but no one has reported seeing or hearing from him since he vanished.

The Tulsa Police Department continues to investigate and considers the circumstances suspicious, with foul play believed to be a possible factor. Does anyone have information about Doran Van Winkle’s movements in May or June 2007, or recall seeing him after those dates?
