A New Jersey man bludgeoned his mother to death Saturday after she tried to stop him from cutting a tattoo clean off his leg, police said.

James Doran, 30, allegedly took off to Pennsylvania after the brutal slaying, where he led cops on a short pursuit and was eventually found covered in blood, stinking of alcohol and “acting erratically.”

Doran is accused of killing his mother, 65-year-old Lillian Doran, inside the Gloucester Township home they both shared with several other family members after the pair got into an intense verbal argument, according to a criminal complaint.

“Witnesses stated that the previous evening, the victim and James Doran had argued about James Doran cutting a tattoo off his leg and walking around the house with a baseball bat,” the complaint stated.

“A witness reported hearing banging sounds and a garage door opening at about 4 am.”

When cops arrived at 10 a.m. Saturday, they found Lillian Doran “obviously dead” on her bedroom floor suffering from what appeared to be blunt force trauma, according to the document.

Her car and her son were noticeably absent from the home.

Doran later caught the eye of Pennsylvania state troopers when he was clocked driving the missing car at 112 mph around 5 p.m. that night — more than 200 miles from the murder scene.

He allegedly braked and pulled over when he noticed the cruiser chasing him, but hopped out of the vehicle and fled into the woods.

After a short pursuit, he was taken into custody.

“The operator was covered in blood and was acting erratically. The operator refused to identify himself and the odor of alcoholic beverage was coming from his breath,” state troopers said in a report.

Doran allegedly refused a legal blood draw, despite three alcoholic beverages being in plain sight inside his mother’s car.

A baseball bat was in the trunk. Police did not say, however, whether it was used as the murder weapon.

Doran was charged with the first-degree murder of his mother.

He also faces more than a dozen misdemeanor and summary charges, including recklessly endangering another person, evading arrest and DUI, reckless driving and resisting arrest in Pennsylvania.

A judge denied bail for the alleged killer because “proof is evident and presumption great that defendant will not comply while on bail,” court records show.

Doran is being held in Bedford County, Pennsylvania while he awaits extradition to New Jersey.
