Deputies said someone waded through a mile of marshland overnight to get to the back fence of the sanctuary, where they cut open the fence and killed the deer with some kind of instrument.

Deputies say the person then cut the animal's head off.

"If you're gonna eat the meat, you take the body not the head," said J.J. Laine, Harris County Precinct 5 Assistant Chief. "We don't know if it's a trophy thing, if it's a ritual thing. We just, at this point, don't have any idea why it was done. It's just so senseless."
