Two Philadelphia-area doctors are dead after one opened fire on the other and then killed himself, officials said Wednesday.

Payman Houshmandpour, 32, was leaving his condo in Voorhees, N.J., for work at nearby Virtua Hospital when a former colleague ambushed him in his car, NBCPhiladelphia.com reported, citing the Camden County prosecutor's office.

"The first two shots were like a second after each other, and then he just unloaded like four or five more shots just like instantaneously -- bang, bang, bang, bang, bang," neighbor Ron Gorman told reporters. "The guy just went haywire, that's what it sounded like anyway, you know, he was on a mission."

Police responding to a witness report of the fleeing vehicle stopped Giocondo Navek, 39, a short time later.

When ordered out of his car, he shot himself, police said.

The two had previously worked together at Virtua, though Navek hadn't been employed there for nearly 18 months.

Houshmandpour was married and had a 1-year-old child, NBCPhiladelphia.com reported.

Some neighbors said the two doctors had a falling out months ago, but no details were available. Police had not provided any motive.
