HODGKINS, Ill. (AP) — Two people found dead in an employee parking lot at a UPS facility in suburban Chicago have been identified, authorities said.

Barbara Phillips, 30, and Fabian Young, 27, were pronounced dead at the scene in Hodgkins, the Cook County medical examiner’s office said Tuesday.

Hodgkins police received a report of shots fired shortly before 1 p.m. Monday. Spokesman Rodney Cummings said when officers arrived, they found two people unresponsive on the ground. Paramedics at the scene pronounced the two dead. A semi-automatic firearm was recovered at the scene.

Investigators said the incident was being investigated as a murder-suicide, Cummings said.

Phillips was a UPS employee, police said.

“We are deeply saddened by the incident that occurred this afternoon, and we are cooperating with the responding authorities,” UPS spokesman Matthew O’Connor said in a statement, adding the company couldn’t comment on the investigation into the shooting.

The Village of Hodgkins, about 14 miles (22 kilometers) southwest of Chicago, has a population of about 1,800.
