Matthew Hertgen, 31, said nothing during the brief videoconference hearing — during which both the prosecutor and defense asked for about a week-long delay to prepare and review evidence in the case.

Judge Amber Gibbs agreed, and set the next in-person court date for March 6 in Mercer County Superior Court.

Jason Matey, the lawyer defending the alleged cannibal killer, also said he plans to meet his client in jail on March 4.

Hertgen was been charged with murder for the gruesome Saturday night massacre in which he allegedly beat and stabbed to death his brother, Joseph Hertgen, with a golf club and a knife.

Then he set the family cat on fire and tore out his brother’s eyeball and ate it, according to police sources.

Officers found a bloody knife, fork and plate near Joseph’s body, the source said — which has led cops to believe Hertgen consumed the missing organ.

If convicted of the heinous crimes, Hertgen faces 30 years to life in prison.

The charges have stunned those who knew the well-heeled family, which lived in a $1.1 million home in Toms River before moving into a ritzy Princeton apartment blocks away from the Ivy league university.

“It’s incredibly tragic,” a high-ranking police source told The Post. “Matthew Hertgen came from what appeared to be a perfect, all-American family. No one could have predicted something like this would happen.”

Both Hertgen brothers were soccer standouts at Toms River North High School and later played in college: Matthew at Wesleyan University and Joseph at the University of Michigan.

After graduation, Joseph worked as an analyst with Red Bank, NJ-based asset management firm Locust Point Capital, the company website said.

His brother, meanwhile, was arrested for drunk driving in South Jersey in February 2017 and lost his license for three months.

But other than that and a few traffic tickets, Hertgen did not have any run-ins with the law.

That all changed Saturday, when Hertgen called the cops to report a dead body and a fire inside the upscale Michelle Mews apartment complex off Witherspoon Street, where units go for up to $2 million.

When they arrived, officers discovered the grisly scene — which one source called “gruesome” and “way overboard.”

Months before the killings, Hertgen had posted chilling poems to Facebook that described blood oozing out of eyes and “knives sharpening.”

But little information has come out about what prompted the alleged killer’s disturbing descent into homicidal madness.

The brothers’ former high school soccer coach, Joseph Mahon, said Hertgen seemed normal back when he was striding through the halls of Toms River North.

“It’s devastating,” Mahon said of the killing. “I just can’t wrap my head around it right now.”
