Camden County prosecutors are now trying to determine if they will seek to try him as an adult, and upgrade charges in the beating death of 53-year-old James Munter (pictured, above left).

Both the prosecutor and defense attorneys are calling the case a tragedy.

Munter's family wants the death penalty, NBC 10 reported.

Prosecutor James Lynch is still investigating whether they will seek to have the teen tried as an adult and if more serious charges are warranted.

"We are looking for justice," Lynch said. "The whole thing is a terrible tragedy, a terrible tragedy."

NBC 10 is not identifying the teen because he is a minor.

The teen's defense attorney Jeff Zucker told NBC 10 that the 17-year-old is remorseful for Munter's death on Monday.

"In my opinion, what's right is charges be dismissed. He was acting in self-defense. He feels remorse for the family, but he was run down and chased for three miles," Zucker said.

Police report the 17-year-old cut Munter off at a gas station, and a chase ensued on the White Horse Pike, where Munter followed the teen to his home. Investigators said Munter then hit the teen with his car. The teen, who is 6 feet 6 inches tall and 300 pounds, was knocked to the ground and suffered bruises, according to his attorney.

"He didn't know if the man would back up and try and run him over, or whether he had a weapon, so he defended himself and hit the gentleman two times. Unfortunately, they were fatal blows," Zucker said.

An autopsy report showed Munter died of blunt trauma to the head.

Prosecutors are reviewing the case, and interviewing witnesses, including the teen's father.
