The Long Island mother accused of torturing and killing cats and dogs and forcing her children to take part in the abuse might plead not guilty by reason of insanity. After getting hit with additional felony charges of animal cruelty and child endangerment yesterday, the lawyer representing Selden resident Sharon McDonough said he is "considering an insanity defense" for his client, who so far has pleaded not guilty, according to 1010WINS. Investigators uncovered the remains of 42 animals in her backyard after her son alerted authorities, claiming his mother "would buy the dog, treat it like it was the greatest dog in the world for a few days, then they would sit in the cage until she decided to kill them."
