WOODBURY — A woman who felt she got second-class treatment after a threesome retaliated by trying to burn down her boyfriend's home, police said.

Tasia Young, 33, showed up at Woodbury police headquarters Tuesday to confess she set the April 7 fire on the unit block of East Centre Street, according to a probable-cause affidavit.

Young told police she agreed to a threesome with her boyfriend and another woman on April 6, but seethed with anger after her boyfriend sent her home in a cab while letting the other woman stay.

The next day, Young returned to Woodbury feeling "like she needed to hurt somebody," according to the affidavit.

She told police she was "going through a lot" and decided to "burn his house down," the affidavit says.

After a stop at the Conoco Gas Station on Mantua Avenue to buy matches and lighter fluid, Young went to her boyfriend's duplex to carry out her plan, the affidavit said. Police later obtained surveillance video of Young purchasing the items.

Young emptied the lighter fluid on and under the front door, lit a tissue with a match and tossed it toward the door, police said.

"Young even demonstrated in the interview how she sprayed the lighter fluid on and underneath the door," the affidavit said.

After starting the fire, she threw out the container of lighter fluid on the way to her cousin's home on the 400 block of Salem Avenue, according to the affidavit.

Young's boyfriend was sleeping inside the East Centre Street duplex when he heard fire alarms and called 911. Young told police she heard the sirens of responding fire trucks, then fell asleep at her cousin's home.

Police and firefighters responded to find the duplex ablaze at 10:40 p.m., evacuating six people who lived in the apartment next to Young's boyfriend.

The fire caused extensive damage to the building, displacing all the residents, according to the affidavit.

Young is charged with aggravated arson, aggravated assault, criminal mischief and other offenses. She is being held in Salem County Jail, according to public records.
