Gruesome Details, Weapon, Motive In NJ Double Murder Documented In Police Report

HILLSBOROUGH, NJ — Two Hillsborough parents were beaten to death in the face by their son so badly that they needed to be identified by their dental records, according to new details released in police documents. Authorities say the 37-year-old man also had a written "wishlist" in which one of the entries was "to kill someone and get away with it."

Patrick J. Lin was charged on Jan. 16 with two counts of first-degree murder of his parents, David Lin, 69, and Jean Lin, 69, in September 2025. He was also charged with one count of first-degree attempted murder and two counts of third-degree possession of a weapon for an unlawful purpose. The charges were announced on Wednesday by Somerset County Prosecutor John P. McDonald.

The Affidavit of Probable Cause obtained by Patch details the circumstances surrounding the deaths of Lin's parents and the attempted murder of a Hillsborough police officer.

On Sept. 25, 2025, at 4:12 p.m., Hillsborough Police received a call asking for a welfare check for a resident of a home on Cornell Trail. After being unable to contact the residents, officers eventually went into the home through an unlocked rear sliding door around 6:30 p.m.

As police checked the second floor, Lin came out of his bedroom with a knife in his hand and lunged at a Hillsborough Police Officer, according to the documents.

One officer fired his gun at Lin, who dropped the knife, picked it up, and turned to face another police officer. The officer fired at Lin again, according to the documents.

Police began life-saving measures on Lin for his gunshot injuries before he was taken to an area trauma center, where he was listed in critical condition.

As officers checked the rest of the home, they found Patrick's parents, David and Jean Lin, "in separate bedrooms, both in their beds with their faces mutilated, caved-in, apparently bludgeoned to death," according to information from police.

No one else was found in the house, and there were no signs of a break-in.

The parents, who were "initially unidentifiable," were pronounced dead at the scene and ultimately identified later through their dental records, according to the affidavit. An autopsy determined that the cause of death was blunt force trauma to the head and deemed a homicide.

Authorities also found blood spatter consistent with impact spatter and cast-off patterns found in both bedrooms, police said.

Three baseball bats were found in Lin's bedroom closets, one of which had a presumptive positive result for blood. There was also a crescent-shaped bloodstain on the floor of Lin's bedroom consistent with the tip of a baseball bat, police said.

An investigation afterward found that Lin had planned on fleeing after the murders. Evidence reportedly found Amazon orders for meals ready to eat and two knives. He also reportedly made two withdrawals from a bank totaling $700.

A family vehicle was also reportedly parked "strategically" around the block with newly purchased clothing and another baseball bat.

A notebook found inside Lin's bedroom had a wishlist. Number two on the list was "to kill someone and get away with it," according to the documents.

On Jan. 16, Lin was served with his complaint in a local hospital, where he is currently listed in stable condition and guarded by the Somerset County Sheriff’s Office.

Once Lin is discharged from the hospital, he will be lodged in the Somerset County Jail. Lin will be scheduled for a pending court hearing on this matter as directed by the court.

The officer-involved shooting investigation is being conducted by the New Jersey Attorney General’s Office.
