LAS VEGAS (KTNV) -- Las Vegas police are after the person who tortured a cat and then left it hanging on a fence.
Police have given 13 Action News graphic pictures of what they found in an attempt to identify the cat.

The sickening discovery was made last month near Alta Drive and Jones Boulevard.
"This is obviously a heinous case because this cat was captured by an individual, taken into a yard, and viciously killed," said Robert Sigal with the Las Vegas Metropolitan Police Department's Animal Cruelty Unit. "We believe this cat was alive when he was hung and suffered greatly during this ordeal."
Now, a $1,000 reward is being offered to anyone who knows something about the gruesome crime.
"We're running into a brick wall trying to find out who did this," said Democratic State Sen. Mark Manendo.
The concern for police is if they never find the suspect, the crimes could escalate.
"They're going to become the people that commit sexual assault," Sigal said. "They're going to become the people that commit homicides."
It's been weeks, and the outrage is growing among animal activists and neighbors.
"Cruelty is cruelty," said Ray Parker, who lives in the neighborhood. "Stop it. That's my message to that person. Stop that."
Police urge anyone with information to call Crime Stoppers at (702) 385-5555.
