MERRILL, Wis. (WSAU) - A Wausau man will stand trial for killing his mother last summer.

Lincoln County Judge Glenn Hartley found probable cause to bind Chase Boruch over on a first-degree intentional homicide charge. The 24-year-old stood mute and Hartley entered a not guilty plea on his behalf.

Hartley refused to lower a $2 million dollar cash bond.

A pre-trial conference is scheduled for March 24th.

Prosecutors allege that Boruch staged Sally Pergolski's drowning death in Moraine Lake on June 6th to collect more than $1 million in life insurance.

Defense attorney John Voorhees asked Hartley to dismiss the charge for a lack of sufficient evidence.

"We don't really have specific facts that may explain how, where and why this happened," the Rhinelander-based public defender said.

Hartley denied the motion.

Four witnesses testified, including the forensic pathologist who conducted Pergolski's autopsy, the 9-1-1 dispatcher who took Boruch's call for help, and two sheriff's deputies who investigated the death.
