PICTURED: The stone-faced mugshot of New Jersey mom who ‘forced child to wear dead dog’s shock collar’

A stone-faced New Jersey mother was arrested after she allegedly forced her daughter to wear a shock collar that once belonged to the family's dead dog. 

Kimberly Cruz-Feliciano, 30, was taken into custody on Tuesday after her child allegedly showed up to show up to Cap May City Elementary School with ‘visible marks on their body' the day before, according to 6 ABC. 

Cruz-Feliciano's mother Sonia Feliciano, 59, was also arrested. 

The child allegedly had to wear the collar while they were at home and would receive shocks every time they would upset their mother, the outlet reported. 

Cruz-Feliciano, who was born in Puerto Rico, kept the collar charged after their family dog died and stored it in a drawer with the late pet's other belongings. 

She also allegedly threatened the child with more violence if they told anyone, prosecutors said. 

Police say the mother admitted to them that she abused her child and had asked her mother to dispose of the collar, according to 6 ABC. 

Cruz-Feliciano was charged with endangering the welfare of a child and hiding evidence and is being held at Cape May County Correctional Center.

The child's grandmother was charged with tampering with evidence and hindering. 

Following those charges, the grandmother, who witnessed the abuse, was released from custody ahead of her court dates, according to 6 ABC. 

Neighbors were shocked to hear what was happening behind Cruz-Feliciano's front door. 

‘It's just sad. I hate to hear something like that, I really do,' one said. 

‘And it's right here in the neighborhood, and I did not know that.'
