Camden County Prosecutor's spokesman Jason Laughlin says authorities are not looking for a suspect. But he would not say whether it was believed to be a murder-suicide.
Laughlin says the shooting was reported a little before 1 p.m. at the Pennsauken office of Dr. Michelle Liggio and that no patients were present.
Investigators created a perimeter around the building and did not enter for about 30 minutes until deeming it safe.
The identities of the victims are not being released until relatives can be notified.
