Fabian Henderson, the Brooklyn man who threw a 1-year-old dog off a roof this summer, failed to show up for his sentencing yesterday — thereby voiding the plea agreement that would have spared him from serving jail time.

Henderson, 20, pleaded guilty last month to aggravated animal cruelty, and in exchange got a deal that banned him from owning a dog again but allowed him to remain free. Skipping court, though, means there is now a warrant out for Henderson’s arrest, and he could now face up to four years in jail, the New York Daily News reported.

“What do you expect from somebody who would throw a dog off a roof,” said one of the animal rights activists who attended the sentencing hearing.

In June, Henderson threw his pit bull-terrier mix, Oreo, off the roof of a six-story Red Hook public housing project. The dog survived injuries that included shattered legs, bruised lungs and internal bleeding, but last month ASPCA officials had the dog euthanized because she had become too aggressive.
