UPDATE: Princeton Panera Gunman Identified After 5-Hour Standoff

PRINCETON, NJ — The gunman killed in a five-hour standoff Tuesday at Panera Bread on Nassau Street in Princeton has been identified, and some new information on his background has been released.

Scott Mielentz, 56, who formerly lived in Newtown, Pa. and most recently lived in Lawrenceville, has been identified as the gunman. He was killed following the standoff at the Panera Bread restaurant, the Attorney General's Office announced on Wednesday.

Mielentz worked in IT and suffered from PTSD from his Army Ranger days, and physical injuries caught up with him, according to nj.com. He was a father of two who suffered from hallucinations, anxiety and depression, according to information found in public records reported by nj.com.

Little is otherwise known about Mielentz or what sparked the standoff in the first place. A pre-trial conference was scheduled in December for a Pennsylvania bankruptcy court involving Scott L. Mielentz.

During the standoff, an officer on the scene reportedly told the Princeton Packet that the man appeared to be suicidal. Planet Princeton reported that he was a veteran.

The Office of Attorney General, meanwhile, noted that it establishes strict procedures for conducting investigations into the use of deadly force by police. The office is required to review all investigations, and in some instances, conduct them.

The office's directive on police-involved shootings "provides that, unless the undisputed facts indicate that the use of force was justified under the law, the circumstances of the incident must ultimately be presented to a grand jury, composed of 23 civilians, for its independent review," the Attorney General's Office said.

Mielentz initially entered the restaurant at about 10 a.m. Tuesday morning. Customers and employees were able to flee the building, and police secured the perimeter of the restaurant, according to the Attorney General's Office.

During the next five hours, police negotiated with Mielentz in an attempt to get him to surrender peacefully. Those attempts were unsuccessful, and the standoff ended when he was fatally shot by police at about 3 p.m., the Attorney General's Office said. Mielentz was pronounced dead at the scene. No one else was injured in the incident.

Nassau Street was closed for nearly 13 hours on Tuesday during the standoff and the investigation that followed. Two buildings at Princeton University were closed during the standoff.

Surrounding businesses were also evacuated during the standoff. Princeton Public schools were under a shelter-in-place, but dismissal and after school activities continued as scheduled.
