The Ontario Special Investigations Unit (SIU) announced Wednesday it “has determined there are no reasonable grounds to lay criminal charges against a WRPS officer in relation to the man’s death.”
Helen Schaller, 58, was gunned down in a parking lot in Preston on April 17, late in the afternoon.
On April 27, the SIU says Waterloo officers had the suspect in the killing under surveillance and were waiting for an appropriate time to arrest him.
It is believed that he had discovered their presence and drove his Toyota RAV4 into a wooded area behind the UPI gas station on Franklin Boulevard.
His vehicle got stuck and police contained the area, SIU said.
According to the SIU, as police closed in, the man shot himself.
The man was transported to Cambridge Memorial Hospital where he was pronounced dead.
The SIU did not release the man’s identity.
On April 29, police announced they were no longer searching for suspects in connection with the Schaller killing.
The SIU is an independent agency that investigates incidents involving police that have resulted in death, serious injury or alleged sexual assault.
