New Jersey authorities say they uncovered appalling, yearslong abuse of an 18-year-old woman at the hands of her mother and stepfather who chained her to a padlocked bathroom and forced her to stay in a dog crate.

When not in those horrid conditions, she lived in a room with only a bucket for bathroom use and an alarm system that alerted her captors if she tried to leave, cops allege.

The victim escaped to freedom on May 8 and ran to the home of a neighbor, who then called police, according to the Camden County Prosecutor’s Office. Now the suspects, 38-year-old Brenda Spencer and 41-year-old Branndon Mosley, are facing a slew of charges including kidnapping, conspiracy to commit kidnapping, aggravated assault and endangering the welfare of a child. Mosley also stands accused of aggravated sexual assault and endangering the welfare of a child with sexual contact.

According to cops, the victim did not detail the full extent of her abuse at the Gloucester Township home until Saturday, two days after her escape. Investigators learned the alleged abuse started around 2018 when Spencer, the victim’s mother, removed the victim, who was then in sixth grade from school and “confined” her inside the home. The victim was forced to live in a dog crate for about a year and only let out “periodically,” prosecutors said. Later, she allegedly stayed chained inside a bathroom and only left when family visited the residence.

“At other times, she was forced to live in a bare room with just a bucket to use instead of a toilet,” prosecutors explained. “She explained the bare room had an alarm system that would alert Spencer and Mosley if she tried to leave.”

Mosley, the victim’s stepfather, also allegedly beat her with a belt and sexually abused her.

When cops searched the home, they found there was also a 13-year-old girl living there. They were allegedly living in “squalid” conditions with several dogs, chinchillas and other animals. Detectives arrested Spencer and Mosley on Sunday.

“What this young woman survived was absolutely horrific,” prosecutor Grace MacAulay told reporters at a press conference.

Local NBC affiliate WCAU spoke with the neighbor who helped rescue the victim.

“I wish I knew what was going on before,” she said. “Otherwise, I would have reported it.”
