Nearly a dozen animals were found decapitated and skinned on the side of a Superior Township road Thursday morning, where authorities have an ongoing investigation of similar discoveries.

A driver spotted the dead animals -- including two skinned foxes, two decapitated deer, a coyote intact and five skinned coyotes -- in the area of Gotfredson and Warren roads, Local 4 learned.

Authorities have been investigating after a terrier mix was found decapitated along a stretch of Harris Road Wednesday evening and a rotweiler was found in a similar condition on March 16, Local 4 reported.

"This was someone's pet. This dog was healthy and fat," said Julie Curtis of the Huron Valley Humane Society about the terrier mix.

The humane society responded to Harris and Geddes roads in Superior Township on March 16 to find a female rottweiler bound by her feet with duct tape and decapitated. The dog was lying next to five skinned coyote carcasses, according to a Humane Society of Huron Valley news release.

"I think it's the (fur) trappers maliciously killing them, and they're family pets," said Curtis.

Though trapping season begins in October and ends March 1, humane officials say these are the first instances involving a household pet.

Local 4 viewer Mark Sondergaard tipped the Humane Society in the discovery Wednesday evening. He saw a news report on Tuesday, then discovered the terrier mix a day later, according to the station's reports.

Sondergaard said he has a Jack Russell terrier, and it is "a little close to home for this to be happening."

Curtis said the Humane Society received more than 60 tips in a 24-hour period Thursday. A reward, which started at $500, has increased to $6,100 for information leading to an arrest and conviction, according to Curtis.
