David Berkowitz, the infamous “Son of Sam” killer who terrorized New York City in the 1970s, is now making a jaw-dropping prediction from behind prison walls.

The 72-year-old convicted serial killer says he believes he is headed for heaven.

But one of the men who survived his bloody rampage has a very different view.

“My home is in heaven, not in the Bronx,” Berkowitz wrote in an email to The Post from Shawangunk Correctional Facility, the maximum-security prison in Ulster County where he has spent decades locked away.

The stunning claim comes nearly 50 years after Berkowitz’s terrifying shooting spree left six people dead, seven others wounded, and an entire city afraid to go outside at night.

Berkowitz, who says he found Jesus in prison, also skipped his latest parole hearing earlier this month. It would have been his 13th shot at freedom since 2002.

But according to the killer, he is no longer chasing life on the outside.

“I am not seeking parole,” he wrote. “I opted not to attend. Right now, I have other things to do, which I feel are more meaningful.”

Berkowitz claimed he is “already free” because of his faith, saying the only place he is looking forward to going is heaven “to be with the Lord.”

That declaration did not sit well with Robert Violante, one of the last victims Berkowitz shot during his reign of terror.

Violante, now 68, was on a date with 19-year-old Stacy Moskowitz in July 1977 when Berkowitz opened fire on them as they sat in a parked car. Moskowitz was killed. Violante was shot in the head and left with devastating injuries, including the loss of most of his vision.

When he heard Berkowitz’s claim about heaven, Violante did not hold back.

“That takes some pair of balls, to say the least,” he told The Post.

“I sincerely doubt he is going to heaven,” he added. “He is lucky he is not already in hell.”

Berkowitz’s new religious persona is a chilling contrast to the monster who once stalked the streets of New York with a .44-caliber revolver.

His killing spree began on July 29, 1976, when he targeted 18-year-old Donna Lauria and 19-year-old Jody Valenti as they sat in a car. Lauria was killed. Valenti survived.

Over the next year, Berkowitz struck again and again across the Bronx, Brooklyn and Queens. His attacks sent shockwaves through the city.

Young women with long, dark hair were especially terrified after reports surfaced that the killer seemed to target them. Some cut their hair. Others bought blond wigs. Nightlife dried up. People were afraid to sit in cars. The city was gripped by panic.

At first, the press called him “The .44 Caliber Killer.” Then Berkowitz gave himself the name that would make him infamous.

After murdering Alexander Esau, 20, and Valentina Suriani, 18, he left behind a deranged note at the crime scene.

“I am a monster. I am the Son of Sam,” he wrote.

He also claimed he loved to hunt and prowled the streets looking for victims.

Berkowitz later said he was driven by demonic forces and claimed a neighbor’s dog had ordered him to kill. He has since said he had made a “pact with the devil,” telling the parole board in 2024 that he was “ashamed” of his crimes.

But for survivors and victims’ families, no prison conversion can erase the horror he caused.

His final attack came on July 31, 1977, when he shot Violante and Moskowitz after they had gone to see the Martin Scorsese film New York, New York.

Violante later recalled waking up covered in blood.

“When I came to, I couldn’t see anything,” he said in a past interview. “My face was covered in blood. The first thing I remember was Stacy moaning because she was shot in the head.”

Moskowitz died the next day.

Berkowitz was eventually caught after a parking ticket placed him near the scene. Police traced the lead to his Yonkers home, where he was arrested.

“I am Sam. David Berkowitz,” he reportedly told police.

The former Bronx postal worker was sentenced to 547 years in prison.

Now, decades later, Berkowitz says prison is where he belongs because he believes he has a spiritual mission behind bars. He claims he works with troubled inmates, preaches the gospel and serves as an elder in a prison congregation.

“My work is in prison where God has His people confined,” he wrote. “These men need guidance, help, and encouragement.”

“I’m an elder, and this is my calling,” he added.

But Violante is not buying the heavenly ending Berkowitz is predicting for himself.

For the man who still lives with the damage from that bloody summer night, the Son of Sam’s fate is not up for debate.

“He is only going to go to hell one day,” Violante said. “And that’s it.”
