Police have charged a 48-year-old man with murder over the death of a man found in a decomposed state in his Gold Coast home.

Police found Tomislav Nemes’ remains in his home at Benowa, on Edinburgh Street, during a welfare check on April 17.

A crime scene was declared, and Operation Victor Countryside was established to investigate the circumstances of his death.

Police believe his wife, 70, and son, 48, lived alongside his remains for more than a year, failing to disclose Nemes’ death to family or the authorities.
