A man from Revere pleaded guilty to abandoning his dog on the edge of a beach and leaving him to the mercy of the next high tide. Elisa Pacheco-Osario, 29, was convicted on charges of animal cruelty and dog tethering. The dog, described as a pit bull mix, was found chained to an exposed steel rod protruding from the Winthrop Parkway ramp at Short Beach in August 2021 with a metal chain around its neck and a heavy rock attached to it. The man was identified using surveillance footage from nearby homes. When asked why he left the dog at the beach, the man said he “couldn’t keep the dog any longer.” He was sentenced to one year in prison, suspended for two years providing he pays restitution and does not own any animals. He was also ordered to complete an online animal cruelty prevention and education program.
