Dr. Conrad Murray’s defense team has earned another enemy – the animal right’s group PETA - for their testing of the powerful anesthetic Propofol on beagles.

PETA, People for the Ethical Treatment of Animals, President Ingrid Newkirk exclusively talked to Breaking Celebrity News and slammed the doctor, who is accused of killing Michael Jackson. 

“Dr. Conrad Murray and his defense team should do time for this act alone. Poisoning and killing dogs will not change what is already known about propofol—its hazards are well documented,” she said.

As Breaking Celebrity News exclusively reported, as source close to Dr. Murray revealed that Beagle dogs had been used to test the drug as attorneys tried to build their defense of the beleaguered physician.

“A study was done on Beagle dogs to determine how much Propofol would have to be orally consumed to cause death. The only other study that had been done on the oral ingestion of Propofol was on pigs rectums. The study definitely involved more than two dogs. It's unknown if the dogs died, or suffered any harm," the source said.
