The New Jersey teen driver accused of deliberately hitting two 17-year-old girls had expressed an unsettling fixation with one of the victims and her family in a recorded livestream before the deadly crash.

In a Sept. 23 YouTube video viewed by The Post, Vincent Battiloro mentioned harboring a “vengeance” against Maria Niotis. He shared that he had pranked her by ordering a pizza to her house, claiming she had made accusations against him that caused trouble at school.

He also appeared to admit on the same video he lurked outside her house a previous time.

Now, the 17-year-old driver is facing two counts of first-degree murder for allegedly striking Maria and her friend Isabella Salas as they rode their e-bike on Monday evening.

Battiloro claimed in his diatribe that he was falsely accused by the teen and her mom of sending “child pornography” — and wanted to get back at the family.

Later in the video he used what he called a “burner phone” to phone Dominos pizza and make a phony order to the home of the teen’s family.

“So you all know I have a vengeance against this girl for accusing me of sending porn and s—, I’m gonna call a pizza to her house,” he said before he had a message for Maria’s mother.

“You should not have accused me of sending porn and you should not have dragged me into creating a police report … you made a decision making a bad name of myself, you made a bad decision having this girl return to this school without me being there,” he said.

He told a worker at Domino’s that the pizza pies would be paid for through cash once they reach the house.

After he hung up, he and his friend let out a diabolical cackle.

When his buddy suggested Battiloro drive over to her house to witness the pizza being delivered, he explained the last time he did that Maria’s mother caught him snooping.

“I got tracked and the police did what they did,” he said.

It’s unclear what action was taken by authorities at the time with Cranford police stating all questions about the tragic case are referred to the Union County Prosecutor’s Office.

Footage of the rants were first reported by NJ.com.

Loved ones of Maria have claimed since the fatal crash that the 17-year-old gamer was stalking her for months, including sitting outside her home.

Battiloro surreally addressed the crash a day after it happened on another livestream, and denied unspecified allegations against him.

Instead he complained that he’s a nice kid who has been bullied.

He also claimed in a May 13 livestream viewed by The Post that allegations were leveled against him about how he was sending “questionable chats and stuff like that.”

He mentioned both his parents were defending him against what he called “bogus” accusations.

But by June, he claimed “that the case is going to be dismissed and I am not going to be facing any charges,” NJ.com reported, citing a video that has since been taken down.

“I’m basically cleared of any wrongdoing,” he reportedly said.

“Says a lot. Says a lot. If they’re closing the case on me for this and they’re bringing me back to school, it says a lot of how much I was innocent in the first place.”

Messages to Battiloro’s father have not been returned and no one answered when a Post reporter approached the family house this week.

The alleged killer is currently in custody.

His case is a juvenile matter, but he could ultimately be charged as an adult.

While he was initially detained and questioned the night of the crash, he was released pending further investigating leading to the Wednesday murder charges, the prosecutor’s office clarified Friday.
