PITTSBURGH — A judge has found a Tarentum woman not guilty of covering up the death of her infant son last summer.

The child’s body turned up at a Butler County hotel, two days after he died in Allegheny County.

Nicole Dull, 32, was acquitted Thursday by an Allegheny County judge who agreed with her attorney that she shouldn’t have been charged under a law better used to target those who throw away the corpses of children.

An autopsy concluded that Dull’s 5-week-old son died of Sudden Infant Death Syndrome last August.

But Dull and the boy’s father, James Victor Jr., 52, of Tarentum, feared that they would be blamed for his death because of their past drug abuse and dealings with county child welfare workers.

So they instead drove with the body to an Allegheny County motel on Aug. 15, 2012.

They eventually checked out but not before leaving behind a note saying that their son had died but they were not ready to turn over “his lifeless body.”

They drove north and ended up at the Super 8 hotel on Route 8 in Butler Township. Their plan was to commit suicide together, authorities said.

Acting on a tip, township police went to the hotel and found the pair there Aug. 17, 2012. They appeared under the influence of drugs and were arrested.

Inside the room, police found the infant’s body, in a baby carrier that was covered by a blanket.

Judge Anthony Mariani acquitted Dull of misdemeanor charges of concealing the death of a child and conspiracy to hide the child’s death.

Victor in January pleaded guilty to those same two charges, court records showed. He was sentenced to time served, having spent 152 days in the Allegheny County. Additionally, he was placed on one year’s probation.
