An 'administrative review' has been launched by LaSalle Police looking into several unsolved break and enters following the confession of 28-year-old Matthew Brush.
On Monday, Brush was sentenced to life in prison with no chance of parole for 22-years in the death of Cassandra Kaake who was seven months pregnant.
During the police interrogation and Brush's confession which was heard in court during his sentencing hearing last week, Brush admitted to breaking into several homes to satisfy his fetish for women's underwear.
"They will look at the B and E's where underwear was stolen or unsolved B and E's,"said LaSalle Constable Harbinder Gill. "We were aware of some of these, the earliest one I was informed of, was in 2002."
He says the incidents were sporadic but police are looking into about 10 cases.
He points out that Brush was never arrested for the break-ins and there was no record of him in terms of fingerprints.
In some cases, Gill says some women may not even be aware that anything was taken.
Court heard that Brush broke into Kaake's Benjamin Ave home in December 2014 because of his fetish for women's underwear.
When Kaake came home that night, Brush beat her, choked it and killed her before setting the house on fire to try and hide his fetish.
