Murder scene was so horrifying police officer SCREAMED at the sight of it, after teen allegedly killed college freshman girlfriend – with his mom now charged with helping him clean up afterwards

The scene where a Pennsylvania college freshman was found bleeding out in the back of her car was so horrific that a police officer screamed when he saw it, newly released bodycam footage shows. 

Karoline Heintz, 18, was found stabbed to death in the trunk of her gray Jeep on August 20 in California, Pennsylvania – about 36 miles outside of Pittsburgh – according to a criminal complaint reviewed by the Daily Mail.

The young girl, who was slated to play Division II soccer at PennWest University, was allegedly killed by her boyfriend, Royce Moser, also 18.

He and his mother, Rachel Moser, 56, have both been arrested and charged in connection with the suspected murder. 

Rachel helped her son dispose of Heintz’s body after he called her and confessed what he had done, according to the criminal complaint. They have not yet entered pleas.

But now, chilling police bodycam video obtained by the Daily Mail has revealed the moment officers discovered Heintz in the back of her car that night. 

A male officer with the California Borough Police Department searched an area near the California Public Library after Heintz’s parents reported her missing and stated that her Apple AirTag was pinging near the location, the cop said in the clip. 

Once he spotted her car, he ran toward it and discovered Heintz’s body, screaming to his partner and into his radio at the top of his lungs: ‘Hey! I need EMS here right now! I got an unconscious female in the back of the car.’

He and his partner then ran over to a police vehicle and put on latex gloves. 

A dispatcher then asked him: ‘Is she breathing?’ 

‘Negative. I got blood everywhere,’ he frantically replied. 

The responding officer then went back to the SUV and shattered the driver’s side window to gain access to the car. 

After that, he punched in the trunk window before slightly opening the door and closing it quickly.  

Another officer then peered into the car through the broken back window with a flashlight. 

The footage showed firefighters and paramedics rushing to the scene. Her father also responded before being brought to the police station by officers. 

Royce is accused of coercing Heintz to his home before getting angry during an argument, the criminal complaint read. 

He said he then had a ‘demon take over’ and told Heintz: ‘Wait I have something for you,’ before going inside the home and grabbing a knife. 

Royce then came back to the vehicle and stabbed her in the chest, causing her to fall out of the car, before he dragged her to the back of the vehicle and called his mom about the incident, the complaint read. 

The mother and son didn’t initially talk to police about the incident but soon confessed to their role in the killing, prosecutors alleged on Tuesday during a preliminary hearing. 

It is unclear how long he and Heintz had been together.

During the hearing, prosecutors presented six witnesses and 32 pieces of evidence that they say prove that the mother and son worked together to kill and get rid of the young woman’s body. 

Among the pieces of evidence, there were several images of black knives that appeared to belong to a kitchen set, photos previously obtained by the Daily Mail showed.

Other images captured the pair on home surveillance footage after the incident, and them driving in a blue sedan with what appeared to be blue latex gloves on their hands. 

The evidence also documented internet searches and phone history records from Royce’s phone.

At one point, Royce searched: ‘What if a demon controled [sic] yoi [sic] and murder someone,’ the prosecution’s evidence read, among other Google searches. 

Royce has been charged with one count of criminal homicide, two counts of tampering or fabricating physical evidence, two counts of abuse of a corpse, and obstructing the law and other government functions, court records stated.

His mother has been charged with tampering with evidence, abuse of a corpse and obstruction. On Tuesday, another count of criminal use of a communications device was tacked on.

A judge has upheld all of the charges filed against them. 

Heintz’s heartbroken family released a statement through Pennsylvania State Police.

‘This is a parent’s worst nightmare. It has been devastating for family, friends, and the whole community,’ the family said. ‘Karoline was loved by all. She was a kind, smart, beautiful girl. We want justice for our “sweet” Karoline.’

‘Please respect our privacy as we grieve. Any questions refer to the PA State Police.’ 

Heintz studied biology, and after obtaining that degree, she would have attended LECOM medical school in Erie, Pennsylvania, according to her obituary.

She dreamed of becoming a physician one day, it read.

In a statement, the school said it ‘is deeply saddened by the tragic death of Karoline Heintz, who was a first-year student at the California campus.’

‘Our heartfelt condolences go out to her family, friends, and all those affected by this tragedy.’

Friends of her family have gone on to set up an online fundraiser that allows people to send money or a meal to Heintz’s grieving loved ones.

Another donation page, made on GoFundMe, has gone on to raise more than $70,000 for her family.

When approached for comment by the Daily Mail, Royce’s attorney, Jake Mihalov, said he has ‘no comment regarding the matter.’  

The Daily Mail also contacted Rachel’s lawyer for comment. 

Royce and Rachel are due back in court on October 13.
