Three southern Alberta residents are facing multiple charges after a series of copper wire thefts targeting agricultural and oil and gas infrastructure across the region.

The RCMP Southern Alberta District Crime Reduction Unit launched an investigation in May 2026 into a string of thefts and damage in Lethbridge County, the Municipal District of Taber, and Newell County.

Investigators say copper wire was repeatedly targeted at irrigation and industrial sites.

Police say the investigation escalated on May 29, when officers observed suspects actively stealing irrigation equipment from a property near Vauxhall.

Mounties say the suspects fled in two vehicles, with one becoming stuck in a potato field. One man was arrested at that location in possession of stolen copper wire.

A second vehicle attempted to flee through rural roads before being stopped using a tire deflation device and assistance from police dog services. A man and a woman inside that vehicle were also arrested and were allegedly found in possession of stolen copper wire.

Police say further investigation linked the suspects to additional thefts and trafficking in stolen property across southern Alberta.

In one incident, damage to irrigation infrastructure is estimated at more than $96,000, with officials warning the destruction could impact crop yields and cause significant agricultural losses.

David Dyck, 27, of Lethbridge, Gerhard Martens, 34, of Raymond, and Kaylee Grisdale, 24, also of Raymond, are each facing charges including theft over $5,000, mischief, and trafficking in property obtained by crime. Martens also faces additional charges, including flight from police, dangerous driving, and resisting arrest.

The three accused were released following judicial interim release hearings and are scheduled to appear in the Alberta Court of Justice in Taber on July 14.
