Updated:HALL COUNTY,None - A Hall County family has spent nearly a year searching for answers in the mutilation deaths of their cattle.
Kathy and John Cooper said they discovered their latest dead cow on their pasture on Monday. It was the 20th cow they've lost, and once again someone had removed its genitals and udders.

"It's just frustration like somebody robbed you," John told Channel 2's Kerry Kavanaugh.
The Coopers said they believe someone is poisoning their cattle then mutilating them in the middle of the night.
"It's almost like a surgically removed cut," Kathy said.
The couple has called the Hall County Sheriff's Office after each incident, but authorities are just as confused. Investigators said they're stumped because the culprits don't even leave behind any footprints.
"They are like us, they scratch their heads and can't make sense out of it," said John.
The Coopers said they try to ride the pasture more frequently and look for tracks or clues, but so far, they haven't found anything.
"It's a waste. They're 700-800 pound cows laying on the ground that nobody benefits from," said Kathy.
The Coopers are offering a reward for information that leads to an arrest. Anyone with information is asked to call the Hall County Sheriff's office at 770-531-6879.
