Several thousand minks that vandals freed from a central Minnesota farm have been recovered, but "the vast majority" of those died soon after recovery, authorities said Tuesday.
Under cover of darkness late Sunday or early Monday, perpetrators invaded Lang Farms near Eden Valley and set loose about 38,000 fur-bearing minks valued at more than $750,000.
Stearns County Sheriff Don Gudmundson said he's convinced that animal rights militants are responsible for the crime.
As of midafternoon Tuesday, the farm's recovery effort has collected 5,500 of the minks, said chief sheriff's deputy Jon Lentz.
"The vast majority are expiring shortly after being recovered," Lentz said. "It may be due to stress, but the owners are not certain."
Michael Whelan, executive director of the fur-raising industry association Fur Commission USA, said Tuesday afternoon that "mink ranchers from around the Midwest continue to arrive to assist in the recovery efforts."
"As domesticated livestock," Whelan said, minks "are not equipped to live outside the farm environment, where they are fed, watered and cared for daily."
Lentz said no one has contacted the Sheriff's Office claiming responsibility. He said his agency continues to cooperate with state and federal authorities in the investigation.
