Fish and Wildlife officers in southeastern Alberta are looking for someone who has been taking potshots at pronghorn antelope.

Two pregnant doe were found dead on Crown land earlier this week northeast of Medicine Hat. Officials say the shots likely came from a high-powered rifle.

"It appears the person had no real reason to kill them," said Brendan Cox with the province's Fish and Wildlife Department. "Other than some form of inappropriate recreation."

Officials say they believe the shots were fired from a vehicle from the road.

Cox says this is the third incident of pronghorns being shot in this area in the last six months.
