Homicide detectives are questioning a man over the disappearance of a South West father-of-three, as hopes of finding him alive fade. Tony Ditri was last seen leaving Pemberton on Friday afternoon heading to the local tip. Concerns were raised when the 40-year-old failed to show up for a family dinner that night, with his car later found in bushland about 20km from the town site. The West Australian understands the homicide squad launched an investigation into Mr Ditri’s disappearance the following day, after receiving intelligence from local sources about the suspicious disappearance. Detectives have since arrested a Pemberton man in relation to the investigation, however it is understood charges are yet to be laid. It is understood police believe Mr Ditri’s white Isuzu truck was dumped in the bush. Police, State and Emergency Services volunteers and hundreds of Pemberton residents are continuing to comb through the area for any sign of Mr Ditri but Manjimup Shire president Paul Omodei said hopes were fading. “The community is certainly in shock,” he told The West Australian. “Tony is a very well known, loved and respected family man. Our thoughts are with his family and loved ones. “I just encourage everyone to stick together and look out for one another.” Mr Ditri ran a Pemberton handyman business and coached the junior football team. “He is extremely well-known, loved and respected,” local business owner Susanne Peet said. “He is one of the pioneering people in Pemberton ... there are streets in town named after his family. “We are just hoping and praying he is found safe and well.” One of Mr Ditri’s friends said it was “surreal” to be searching the bush “for a sign or clue that can point us in the direction” of the well-loved missing man. “Extremely unusual circumstances — Tony is one of the most genuine humans you will ever meet,” he said. “Someone knows something and if you do please report it to the police.” Police are anyone who has seen Mr Ditri or has information regarding his whereabouts to contact police on 131 444 or Crime Stoppers on 1800 333 000.
