The 29 year old disappeared from Mayfield 10 years ago, on August 7, 2013, and police strongly suspect he was murdered.

To date, his body has not been found, and a reward for information leading to a conviction in the case was increased to $500,000 in 2021.

Detective Acting Inspector Andrew Hanson said while police had significant information relating to the case, stronger evidence was needed.

“We believe $500,000 is a life changing amount, and we are hopeful it may encourage witnesses to come forward,” Detective Acting Inspector Hanson said.

“When a person is missing, the case remains open until we have answers. Our aim is always to try and find those answers, and ultimately provide closure for the missing person’s family and loved ones.”

Crime Stoppers Tasmania CEO David Higgins said information could be reported anonymously.

“If you report anonymously through Crime Stoppers, you can still be eligible for a reward if your information leads to a conviction,” Mr Higgins said.

“I encourage anyone with information about the disappearance of Christopher Watkins to report through Crime Stoppers Tasmania – you do not need to provide your name or personal details.”
