Waterloo Regional Police say a suspect in the murder of Helen Schaller was found Saturday morning with what appeared to be a self-inflicted gunshot wound.

They received information that the man was in a vehicle at a gas station in the area of Franklin Boulevard and Savage Drive.

The Emergency Response Team was dispatched around 11 a.m. to conduct a high-risk takedown.

According to the province’s Special Investigations Unit, the man drove his vehicle into a wooded area and a short time later he was discovered by officers with a gunshot wound.

The 39-year-old was taken to Cambridge Memorial Hospital and was then airlifted to Hamilton General Hospital with what Ornge called critical injuries.

Schaller, 58, was shot in broad daylight in a Preston parking lot in the area of King Street East and Church Street on April 17.

She later died of her injuries.

In the days after Schaller’s murder police released a suspect description and an image of a vehicle the suspect was believed to be driving.

The motive for the shooting is still under investigation.

The man’s name has not been released.

The SIU is now investigating.
