NEW WINDSOR, N.Y. (AP) – A Connecticut man and two other managers of a nail polish factory were shot in the head by a fired employee who then killed himself, police said.

Victor M. Piazza walked through the front door of Verla International at about noon and fired a .38 revolver at co-owners of the Hudson Valley factory and an office manager. Co-owners Mario Maffei, 57, of Greenwich, Conn., and Robert Roth, 65, of Wallkill, N.Y. were in stable condition Monday evening. Office manager JoAnne OBrien, 48, of Greenwood Lake, N.Y. was in critical condition.

Motive unclear

Piazza was arrested in 2004 for having child pornography on his company computer after the company complained to police. He was subsequently fired, said New Windsor Police Chief Michael Biasotti. Piazza was sentenced to 10 years probation and classified as a level two sex offender after pleading guilty to possessing child pornography.

Biasotti said it was too early in the investigation to know why Piazza shot the company officials, though he added: “I’m sure that he was upset at management.”

“We don’t know why this occurred,” Biasotti said.

Orange County District Attorney Frank Phillips said Piazza had no history of criminal violence but was arrested in the mid-’80s for unlawfully dealing with a child. Officials did not have details on that arrest.

Police arriving at the scene found Maffei lying in the parking lot with a gunshot wound to his head. Roth was at the bottom of a stairway. Both men were conscious. OBrien was found slumped in a chair, unconscious.

Verla employs about 400 people.

At about 3:30 p.m., police removed a body in a maroon bag from the factory, which is just outside the old industrial city of Newburgh, about 55 miles north of New York City.

As employees left the factory, they were met by police until it was determined the workers were not involved in the shooting. Later, they were allowed back in to get personal items before they were sent home.

A man who answered the phone at Piazza’s house identified himself as the gunman’s father but declined to give his first name. He told The Associated Press police had informed him of his son’s death, but gave no other details.

A phone listing for Humberto Piazza matches the address and phone number for Victor Piazza.

“Oh my goodness, I don’t know what we’re going to do now,” the man said.

He did not know how long his son had worked at Verla but said there was nothing to indicate he was upset with his former employer.

“Oh, no, nothing like that,” he said.

A call to the company was not answered Monday afternoon.
