A Thunder Bay Police Service investigation into elder abuse has resulted in charges.
 
The investigation began on February 11, 2025, after the Crimes Against Seniors’ Division received a report about an incident that took place on January 30, 2025 at a long-term care facility in Thunder Bay.
 
An 86-year-old resident sustained injuries while in the care of a staff member.
 
Additional unrelated and unreported injuries were later confirmed.
 
No documentation of the injuries was located by officers.
 
The victim died on March 06, 2025 as a result of the injuries.
 
The Thunder Bay Police Service investigation identified the long-term care facility failed to take the reasonable steps to prevent any serious bodily harm or death to residents and attempted to delay and obstruct a police investigation.
 
As a result of the investigation, Marina GILBERT, 52, of Thunder Bay, has been charged with Criminal Negligence Causing Death contrary to section 220 of the Criminal Code.
 
Furthermore, Pioneer Ridge Long Term Care Home has also been charged with:
 
• Criminal Negligence Causing Death contrary to section 220 of the Criminal Code 
• Obstructing Justice contrary to section 139(2) of the Criminal Code
 
The investigation is ongoing and no further information is available at this time.
