MOORESTOWN, N.J. (CBS) — One person is dead and another is in critical condition after a dispute between two employees turned deadly at a business in South Jersey Monday morning, police said.

The shooting happened at about 7 a.m. at Shields Business Solutions on Twosome Drive in Moorestown, New Jersey.

According to investigators, the incident began as an altercation between two employees inside the building.

Investigators said 42-year-old Edgar Figueroa, of Philadelphia, shot his co-worker, 31-year-old Melvin Nieves, also of Philadelphia, four times.

Police said the shooting occurred inside of the building and Nieves, who was not armed, ran out of the building.

Nieves was transported by helicopter to Cooper University Hospital where he is listed in critical condition.

Authorities say Figueroa also made his way outside and eventually took his own life by turning the gun on himself in the outside rear of the building.

Investigators said the deadly shooting was sparked by an ongoing domestic situation.

No one else was injured.

A representative from Shields Business Solutions released a statement that read in part:

“An unspeakable tragedy unfolded here this morning and, first and foremost, we’d like the families of those involved to know that our thoughts and prayers are with them. To our employees, we want to reiterate that their safety is our absolute priority. In order to provide support to our employees today and throughout the week, we have engaged a grief counselor who will be available here at our offices. At this point, this situation is a police matter, and we are working with the Moorestown Police Department.”

The shooting remains under investigation.
