Some of the most notorious murderers in history – including the “Son of Sam” murderer David Berkowitz – could be eligible for release if two parole reform bills under consideration in Albany are approved, critics caution.

One proposal, known as the Elder Parole bill, would allow inmates convicted of violent crimes to seek early parole once they reach age 55 and have served at least 15 years, regardless of the severity of their offenses.

A second measure, the Fair and Timely Parole bill, would direct the state parole board to grant release to inmates unless they are deemed a current threat to public safety, placing less emphasis on the nature of their original crimes.

Both pieces of legislation could lead to the release of inmates serving life sentences, including those convicted of especially brutal killings.

“Consider some of the most heinous and noteworthy people in . . . prison today, they will undoubtedly be released within the next two years if these bills are signed into law,” a law enforcement source told the NY Post.

The Elder Parole bill is sponsored by Sen. Cordell Cleare of Harlem and Assemblywoman Maritza Davilla of Brooklyn.

Under that legislation, inmates granted parole would be placed under community supervision as though they had completed their full sentences. If denied parole, they must receive a written explanation detailing the reasons and would automatically become eligible again after two years.

That process would require victims’ families to repeatedly return to parole hearings to oppose the release of those convicted of killing their loved ones.

The Fair and Timely Parole bill is sponsored by state Sen. Julia Salazar and Assemblyman David Weprin.

The proposal would make it easier for inmates with strong disciplinary records behind bars to be released, regardless of the brutality of their crimes.

Advocacy group The People’s Campaign for Parole Justice says the bill would “provide more meaningful parole reviews.”

Raphael Mangual of the Manhattan Institute said momentum for the legislation appears to be building in Albany and could lead to passage this year.

“I think it’s a real risk, especially given the recent decline in crime in New York City,” he told the NY Post. “I think that might have led to a space where people might be more tolerant than they were five years ago of engaging in this kind of experiment.”

He added: “It really shouldn’t matter how well somebody behaves in prison. You should have behaved before you got there.

“You hear people who will say with very full confidence, including the advocates, that the likelihood of a person reoffending zeros out in older age,” he said. “No it doesn’t. A majority of state prisoners who are released will reoffend.”

One victim’s family member said the possibility of early release is deeply troubling.

“My brother was brutally tortured to death throughout the night,” Michael Pravia, whose 19-year-old brother Kevin was murdered in 2008 told the news outlet. “You know, I just feel like we’re living in a time where it feels like it’s another form of corruption, you know, letting these devils out of prison to harass the masses.

“They will have blood on their hands,” Pravia said of the legislators who pass the bills.

Pravia said his brother’s killer, Jeromie Cancel, showed no remorse.

“He was proud of his crimes,” he said.

Cancel laughed and smiled during his 2010 sentencing, prompting Pravia to shout, “I’ll…kill you!” in Manhattan Criminal Court.

“There is not one ounce of me that thinks he is rehabilitated or has the ability to be rehabilitated,” Pravia, 34, said Thursday. “I think he is truly a sociopath. He’s bragged that he would do it again.”

According to a law enforcement source, Cancel could be eligible for release under the Fair and Timely Parole bill if he maintains a clean disciplinary record in prison.

It remains unclear whether Gov. Kathy Hochul would sign or veto the measures if they reach her desk.

A spokesperson for Hochul told the Post the governor “is committed to ensuring the safety of New Yorkers and will review any bill that passes both houses of the Legislature.”

Republican gubernatorial candidate Bruce Blakeman strongly criticized the proposals and accused Hochul of enabling the release of violent offenders.

“Kathy Hochul has fast-tracked the release of violent criminals – even those who’ve killed police officers – and will certainly grant ‘get out of jail free’ cards to even more dangerous thugs,” he said. “The Hochul pro-criminal era ends the day I take office.”

Among those who could potentially benefit from the legislation is David McClary, who was convicted of killing NYPD Officer Edward Byrne in 1988 and is currently serving a 25-years-to-life sentence.

McClary, now 60, has been denied parole eight times since becoming eligible in 2013, requiring the victim’s family to repeatedly oppose his release.

The Police Benevolent Association has also pushed back against the bills, citing concerns over public safety and justice for victims.

PBA President Patrick Hendry told the Post, “Passing either of these bills would be a cruel and despicable blow to the families of our fallen heroes.

“There is no age and no formula that can absolve cop-killers of their heinous crimes or entitle them to rejoin society,” Hendry said. “We will fight tooth and nail alongside the families of our murdered police officers to ensure [these two bills] do not become law.”
