GRAYSON COUNTY, Texas -- Farm animals were found skinned and dead at the side of a road in Tioga on Sunday.

On Tuesday, another animal was found dead in a different location.

"It's kind of a weird situation," Grayson County Sheriff's Office spokeswoman Capt. Sarah Bigham admitted. "It's not something we run into every day."

The initial call came in on Sunday morning near the intersection of Howell and Buck Creek roads east of Tioga, where three sheep and four goats were found dead in a field.

"Those animals had been mutilated, where their skin and their heads had been removed," Bigham said.

All the meat was left on the animals, and there are no ideas about who did it... or why.

"We are currently investigating that incident as an animal cruelty incident and trying to figure out how the animals got there and why it happened," Bigham said. "The area they were found in is very close to Denton County and Collin County, so we did contact those counties to make sure they didn't have any of those kinds of livestock farms in that area."

Grayson County officials said they received another call Tuesday from someone who said a goat in Dorchester-- near Sherman, about 10 miles away -- was found in the same condition as the other mutilated farm animals. 

The SPCA is helping to investigate these cases.
