A Long Island woman is suspected of torturing and killing as many as 20 cats and dogs — some of them belonging to her neighbors — before burying them behind her home. Animal control investigators unearthed the "gruesome pet cemetery" on Saturday behind 43-year-old Sharon McDonough's Suffolk County house after discovering five malnourished dogs kept in cramped cages inside the residence. According to WPIX, "McDonough frequently involved her children in the animal killings by asking them to hold pets down as she tortured them." Neighbors whose pets have gone missing showed up at McDonough's home hoping to identify their animals. "A couple of people have lost pets," neighbor Angelo Zotto, 70, told the Daily News. "They were up here today with pictures of their pets showing them to the SPCA, wondering if theirs had been found in the backyard."
