William LeRoy Douglas Sr., 63, was last seen on February 4, 2004, at his cattle farm in Woodburn, Iowa. That morning he spoke on the phone with his mother, then hung up to answer the door and was never seen or heard from again. He was wearing black Carhartt overalls, Wrangler jeans, and black boots.

His bank accounts showed no activity after he disappeared and there were no signs of a struggle at the home. Extensive searches of the farm and surrounding areas produced no significant leads. Douglas, known as Bill, was a father of five and was described as hard-working with a close relationship with his children; his daughter Betsy has said she believes foul play may be involved. He was declared legally dead in 2009, and authorities continue to list him as an endangered missing person.

Does anyone who knew Bill, worked on or near that farm, or was in Woodburn in February 2004 have information that could help explain what happened?
