MONROE COUNTY, Miss. (WTVA) -- Tony Wright and Samantha Williams want answers. Their father, William Harold Wright, 69, has been missing for three weeks.
"You go to bed with it on your mind. You wake up with it on your mind. He's a good man. I just want him back," said Wright.
The family decided to increase the reward to $20,000 after spending countless hourse searching for their loved one.
"We rode every road that we know to ride. We've had people call and give us tips and places to look. We actually went up in a helicopter. We've carried four-wheelers in that area where he was last seen. We're to the point now to where we don't know what else to do but this and make a plea to the public that if anybody has seen him to contact the Monroe County Sheriff's Office and the Lowndes County Sheriff's Office," Wright added.
Lowndes County Sheriff's Office Investigator Mark Miley hopes the reward increase will attract new attention to the case.
"It could just make people think well maybe I did see something and maybe this can help and this can lead to something, so they'll call," Miley said.
He was last seen at a lounge on Highway 12 in Caledonia. His 2004 Ford Ranger Edge was noticed at a stop sign on Caledonia-Vernon Road.
Also searching for answers is Monroe County Sheriff Cecil Cantrell. They searched a body of water at the gravel pits on Highway 45 with the help of sonar.
"What we want to do is try to bring some closure and give them a peace of mind of what happened to their father," Sheriff Cantrell said.
Sheriff Cantrell says two people are being looked at as possible suspects in Lowndes County. Authorities with the Lowndes County Sheriff's Office have declined to comment on any suspects.
