RARITAN -- A borough attorney accused of offering to represent female clients at a reduced rate in exchange for sexual favors was found dead in his vehicle Tuesday morning from an apparent self-inflicted gunshot wound to his chest, the Somerset County Prosecutor's Office has confirmed.

Richard P. Schubach, 58, of Stockton was arrested and charged Monday with three counts of fourth-degree criminal sexual contact after he allegedly propositioned a female undercover detective in a sting operation, according to a news release issued Monday.

At approximately 6:51 a.m. Tuesday, Raritan Borough police responded to a welfare check on Schubach, who was thought to have been at his law office at 1124 Route 202, the prosecutor's office stated.

Officers reported finding Schubach at 7:35 a.m. in his vehicle, which was parked outside an office complex adjacent to his law office. He was unresponsive with an apparent self-inflicted gunshot wound to his chest, authorities stated.

The Somerset County Prosecutor's Office Major Crimes detectives responded to the scene, where Schubach was pronounced dead at 8:05 a.m. by Emergency Medical Technicians from Robert Wood Johnson University Hospital Somerset, the prosecutor's office stated.

The exact cause of death is pending an autopsy by the New Jersey Northern Medical Examiner's Office, authorities stated.

Schubach had a wife and two children, a son and a daughter, according to friends.

Authorities said the Somerset County Prosecutor's Office received information in December that Schubach allegedly offered some of his female clients a reduced price for his legal fees in exchange for sexual favors.

On Thursday, a female undercover detective went to his law office under the guise of discussing a criminal matter she was facing. During their first meeting, Schubach told her to return the next day with further documentation about the criminal matter. Prior to her leaving his office, he allegedly asked her to wear something "pretty" for their next meeting.

During that second meeting Schubach allegedly touched her breast and inner thigh. The undercover detective reportedly stated to Schubach, "I don't like this," and attempted to leave his office. As she attempted to leave, Schubach allegedly asked her to "hold on," proceeded to expose her right breast and place his mouth over it, authorities stated.

Before she left the building, Schubach is alleged to have asked her to turn around to face him and he lifted up her skirt, according to authorities.

Schubach had previously been disciplined three times by the state Supreme Court, including two 90-day suspensions on accusations that include failure to perform diligently on his client's behalf, misconduct in a personal real estate transaction with his then-girlfriend and using her funds in personal business transactions and engaging in conduct involving fraud, deceit, dishonesty or misrepresentation.
