A 24-year-old Pennsylvania man was arrested and charged Thursday with the murder of his father, who is a New Jersey resident and doctor, officials said.

Steven Mark Quadrel, 24, of Norristown Pennsylvania, is charged with murder, aggravated assault and other offenses for shooting his father, Mark Quadrel, 58, of Rockaway, on Wednesday, according to a statement from the Montgomery County District Attorney's Office.

When the elder Quadrel arrived at his son's apartment and the two got into a heated argument that caused Steven to grab a gun from his car, return to his apartment and shoot his father multiple times in the head and torso, according to Philly.com.

After walking out his apartment, Quadrel shot a 12-year-old boy on a scooter, officials said. The boy suffered a graze wound to his hand and arm, was treated for the non-life threatening injury at local hospital and was released.

Norristown Police were dispatched to Sandy Street, which is just one block from Quadrel's apartment on East Airy Street, for a report of a man shooting a gun outside, the district attorney's statement said.

When they arrived, they found Steven and a Baretta 9mm semi-automatic pistol with a laser sight hidden behind a parked truck. He was taken into custody by police, authorities said.

Philly.com said that according to court documents, Quadrel repeatedly asked the officers if his father was "OK", but also told them that he had killed him.

Police went to Quadrel's apartment and found the door open and the father's body, the office said.

Dr. Quadrel, who worked at Internal Medicine of Morris County, was mourned by many people on Facebook Friday including one man who called him a "wonderful family man."

Quadrel told police that he shot once at the boy on the scooter because he was "creeped" out by the sight of him, the Philly.com report said.

He was taken to Montgomery County Jail and his first hearing was scheduled for Nov. 9.

Anyone with information about the homicide was asked to call the Norristown Police Department at 610-270-0977 or the Montgomery County Detective Bureau at 610-278-3368.
