The investigation into the mutilated body of a cat found on a fairway at Covington Country Club will move to the St. Tammany Parish Coroner’s Office on Tuesday morning.

The office’s chief pathologist, Michael DeFatta, will conduct a necropsy — an animal autopsy — on Charlie, a 2-year-old pet cat whose body was found split in two this month.

A veterinarian from the Humane Society and deputies from the St. Tammany Parish Sheriff’s Office will attend the necropsy.

Having animals brought to the Coroner’s Office for a necropsy is unusual, but not unheard of.

“We have, in the past, assisted the Department of Wildlife and Fisheries in similar investigations, so this is not a unique case,” Coroner Charles Preston said.

Charlie’s death was likely the result of a criminal act, and killing small animals in such a manner is sometimes an indicator of mental illness, Preston said.
