AUSTIN, Texas >> Six mutilated cows were found dead on different properties along a Texas highway spanning three counties, authorities announced this week.

While investigating the death of a 6-year-old cow, five other similar occurrences were reported along the area near College Station spanning Madison, Brazos and Robertson counties, Madison County Sheriff’s officials said Wednesday in a Facebook post. Similar mutilations have been reported around the U.S. and efforts to coordinate between agencies were underway, the sheriff’s office said.

The 6-year-old cow was found with a “straight, clean cut, with apparent precision” removing the hide around one side of the animal’s mouth, authorities said. The tongue was also removed, with no blood spill. Ranchers reported no predators or birds had scavenged the remains. The cows were found in similar conditions.
