A Long Island woman who is credited with establishing an animal rescue group that saves unwanted horses is accused of euthanizing at least three dogs without a license to practice veterinary medicine, Suffolk County Police announced Thursday.

According to authorities, Mona Kanciper, of Manorville, was charged with three counts of aggravated animal cruelty. In addition, Kanciper was charged with two counts of endangering the welfare of children for performing the alleged euthanizations in front of minors, police said.

The relationship between the children and Kanciper was not immediately known.

The Suffolk County SPCA also charge that the Long Island woman choked a dog to death after incorrectly performing one of the euthanizations.

Kanciper, 48, surrendered herself to SPCA officers on August 8th. She was arraigned Thursday on the animal cruelty charges, police said.

Chief of the Suffolk County SPCA Roy Gross said a search warrant executed at the suspect's home uncovered the remains of horses, euthanasia drugs and syringes.

According her website, Kanciper identifies herself as the operator and president of the New York Horse Rescue Farm located at 15 South Street in Manorville.
