The Lincoln County Sherriff's office held a press conference Tuesday about the recent arrest for First degree intentional homicide of UW-Madison student and Iraqi War Veteran Chase Boruch.
Boruch, 24, was arrested Monday at his West Washington apartment in connection with his mother's death last June.
The criminal complaint states Boruch was with his mother, 63-year-old Sally Pergolski, in their truck when it drove into Moraine Lake June 6.
According to Lincoln County Sherriff Jeff Jaeger, Boruch told police he was able to escape the vehicle before pulling his mother from the sinking truck and dialing 911.
The deputy who arrived on the scene found Pergolski facedown on the shoreline and was unable to resuscitate her, Jaeger said.
In the press release Tuesday, Jaeger said police issued a warrant for Boruch after discovering he had taken out over $800,000 in insurance policies a month before the accident.
Jaeger also said authorities recently received the autopsy report, which stated that Pergolski suffered a brain injury at least two hours before police were notified.
According to the release, Boruch is currently being held at the Lincoln County jail on charges of First Degree Intentional Homicide.
Prior to enrolling at UW-Madison, Boruch attended UW-Marathon County in Wausau, after serving a tour in the Iraq War.
At Marathon County, Boruch served as president of the University of Wisconsin Colleges Student Governance Council.
Another former CSGC president and current UW-Madison senior Dakota Kaiser said he remembered Boruch as ""a really nice kid"" who was quiet, dedicated to his job and ambitious.
""It's really shocking, and it's really strange,"" Kaiser said. ""[Boruch] was in a position of trust and he did a lot of really good things, between his service in the military and the projects he did with student government.""
Kaiser said he knew Boruch primarily through the CSCG, where they had discussed law school, a ""big goal"" in Boruch's life at that time, Kaiser said.
""Seeing this guy you've known as a strong social advocate and someone who really does the right thing in life being arrested for murdering his mother, I guess it's just really a shock,"" said Kaiser.
Boruch is expected in court early Wednesday afternoon.
