A woman already facing a murder charge has appeared before the Mackay Magistrates Court after Queensland Police laid additional drug-related charges as part of an ongoing investigation into the disappearance of a Mackay man. The case remains one of the region's most significant criminal investigations, with detectives continuing to seek information from the public.

The accused, Sarah-Lee Pearl Williams, 46, has previously been charged with the murder of Wayne Pedro Morseu, 71, who was reported missing in November 2025. Police allege Mr Morseu was unlawfully killed, although his body has not yet been located despite extensive searches and months of investigation.

During her latest appearance before the Mackay Magistrates Court, Williams faced additional charges relating to the alleged possession of dangerous drugs and drug-related items. The new charges were formally mentioned before the court, while the existing murder proceedings also continue through the Queensland justice system.

Queensland Police have described the investigation as complex and extensive. Detectives have interviewed more than 120 witnesses and collected over 100 pieces of evidence since Mr Morseu's disappearance was first reported. Investigators continue to examine forensic evidence while following multiple lines of inquiry in an effort to determine exactly what happened.

Authorities have again appealed to members of the public for information that may assist in locating Mr Morseu's remains. Detectives believe even small details could help progress the investigation and provide answers to the victim's family. Anyone with relevant information is encouraged to contact Queensland Police or Crime Stoppers.

The matter was briefly mentioned before the Mackay Magistrates Court, where the accused appeared via video link. The court adjourned the proceedings to allow the case to continue through the legal process. Police emphasised that the investigation remains active and further inquiries are ongoing.

The case has attracted significant attention across the Mackay region because of the lengthy investigation and the continued search for the missing man's body. Police have repeatedly stated that locating Mr Morseu remains a priority, with specialist officers continuing to examine evidence gathered during the investigation.

Authorities reminded the public that criminal proceedings are currently before the courts. The charges have not been proven, and the accused is entitled to the presumption of innocence unless and until proven guilty in court.

Queensland Police said they remain committed to pursuing every available lead and thanked members of the community who have already provided information. Investigators believe continued public cooperation will be important as the case progresses.

The investigation remains ongoing, with further court appearances expected in the coming months. Detectives have indicated they will continue reviewing evidence and following new information as it becomes available while seeking to provide justice for the victim and his family.
