Christopher Thomas, who murdered 10 people -- including 8 children -- in Brooklyn in 1984, was freed from an upstate New York prison in January, prison officials confirm.
Thomas, now 68, slaughtered 2 adults and 8 children in one of the worst mass shootings in New York history.
Thomas shot and killed an entire family in a blood-soaked East New York apartment on a rainy Palm Sunday, according to the NY Post. The children ranged in age from 3 to 14. The lone survivor was a 13-month-old baby girl.
Retired NYPD Detective Bo Dietl described the horrific scene to The Post in 2009.
“One child was eating chocolate pudding, sitting on the couch in a suspended state, with the spoon still in her hand, dead."
He said the tiny victims' faces were frozen in fear after each was systematically shot at close range.
The murders stemmed from an argument Thomas had with the children's father, convicted cocaine dealer Enrique Bermudez.
Thomas was convicted of manslaughter -- also known as hot-blooded murder -- rather than 1st-degree (cold-blooded) murder, which would have resulted in a stiffer prison sentence.
The judge sentenced Thomas to the maximum of 50 years, but the model prisoner was released early for good behavior from the Shawangunk Correctional Facility on Jan. 5 after serving two-thirds of his sentence, said a state Department of Corrections spokesman.
“The parole board did not let him out,” the rep told The Post.
Former NYPD Commissioner Ray Kelly said Friday that Thomas’ "heinous crime" deserved the maximum punishment.
“He doesn’t deserve to be on the street. He killed poor, innocent children," retired NYPD Lt. Herbert Hohmann, who led the investigation into the murders, told The Post on Friday.
The jury said they convicted Thomas of the lesser charge of manslaughter because his heavy cocaine use was a factor in the massacre.
He is believed to be living somewhere in Queens, a borough of New York City.
