Violent Central Park dispute leads to dog's tragic end.

Police are searching for a man who stabbed a couple's dog, Eli, in Central Park after his three off-leash pit bulls attacked the couple's two leashed dogs. The suspect allegedly pulled out a switchblade and repeatedly stabbed Eli, a pit bull-German Shepherd mix, who later died at an animal hospital. Witnesses described the suspect as a man wearing an orange shirt, orange hat, and blue jeans who fled the scene after the altercation. The investigation is ongoing.
