ST. LOUIS (KMOX) -  The reward to track down those responsible for the torture and deaths of several dogs in north St. Louis has now been raised to $10,000 and 500 Euros.

The dollars are from donations being accepted by Stray Rescue founder Randy Grim. Grim says the Euros are coming from The International Animal Rescue Foundation of the United Kingdom.

Grim was among those who discovered the gruesome scene in the 5300 block of Wells Ave. Tuesday.

One dog had been killed by having a window slammed onto its neck repeatedly, and its body was left dangling over the windowsill.

Another had apparently been burned alive.

In all the carcasses of five dogs were discovered in the abandoned residence, described by some as a “gang house”.

One anonymous source told Grim that a sixth dog had also been killed by being hung out of a window.

“The reward (which started at $5,000 on Wed.) has already encouraged people to call with information, and we hope this increase in reward money will motivate citizens to step forward with critical details about the case,” said Grim. “We’re working tirelessly to catch these abusers and get them off our city’s streets.”
