Mark Sheridan Waden Faces Murder Trial After Girlfriend’s 2018 Disappearance

Mark Sheridan Waden, a Zumba instructor from Brisbane, is set to stand trial for the alleged murder of his girlfriend Priscilla Brooten, who vanished in 2018, according to court records and reports from the Brisbane Times.

What Happened in the Police Interview?

During a 90-minute police interview in June 2019, Waden denied involvement in Brooten’s disappearance, stating, “I didn’t do it,” as authorities excavated his property, according to transcripts reviewed by the Brisbane Times. He described their relationship deteriorating after he began a real estate job, which led to less time for social activities. Waden claimed Brooten, a U.S. citizen, had been in Australia illegally and was using him to avoid deportation.

What Evidence Is Being Presented?

The prosecution alleges Waden factory-reset Brooten’s phone after her disappearance and gave it to his new girlfriend, Desiree Hatzipapas. Detective Anthea Johnston questioned Waden about the phone’s fate, noting he claimed it was “pin locked” and reset after Brooten allegedly left it behind. Court documents also reveal Waden admitted to restraining Brooten and slapping her during arguments, though he denied planning her death.

How Did the Relationship Collapse?

Waden told investigators the relationship soured when Brooten discovered he was dating Hatzipapas. He claimed she threatened to destroy his property and that he lied to his real estate employer about missing a listing to avoid losing his job. Brooten’s ex-boyfriend, Steve Thompson, was also mentioned as a financial supporter, according to the interview.

What Is the Current Status of the Case?

Waden, 34, has pleaded not guilty to murder. The trial, set in Brisbane’s Supreme Court, will examine whether he concealed Brooten’s body, potentially in a suburban landfill, as police excavated his yard in 2019. Authorities have not found her remains, and the case remains unsolved. The court heard Waden’s claims about Brooten’s “closed” lifestyle and secretive behavior, including her use of false names.

Why Does This Case Matter?

The case highlights challenges in missing persons investigations, particularly when individuals are undocumented. Brooten’s disappearance, which occurred during a period of strained relationships and legal uncertainties, underscores the complexities of cross-border immigration and domestic violence cases. Similar cases, such as the 2016 disappearance of Australian woman Natalie Wood, have faced prolonged legal battles over evidence and witness credibility.
