Timber wolves that escaped from a zoo in Essex were shot and killed by authorities after an eight-hour search.
Three wolves have been shot dead after they escaped from a zoo in the UK, prompting an eight-hour search throughout the region.
Five timber wolves escaped through a broken fence at Colchester Zoo in southeast England and were noted missing Tuesday morning, the BBC reported.
One animal returned on its own and another was shot with a tranquilizer dart and returned, but the three other wolves suffered more unfortunate fates.

Two of the wolves had made their way to the perimeter of the zoo and were shot and killed, while the final wolf led authorities on an eight-hour hunt, including armed officers and a helicopter while the area was cordoned off, according to the Guardian.
The final wolf was eventually located in thick underbrush and shot dead. Zoo officials have said they will conduct a full investigation into the incident. It remains unclear why the fence was broken.
Why shoot the animals? The Colchester Zoo explained its reasoning in a statement on its website: "Unfortunately, an anesthetic dart takes 15 minutes to take effect and may not work at all in a stressed animal so two wolves that had left the perimeter of the zoo had to be shot. They are wild animals and in an unpredictable situation they would have posed a risk to the public."
