A neighbor charged with killing an 11-year-old girl in New Jersey made his first court appearance Friday — and was met by the victim’s mom who shouted, “I hope you rot in jail.”

Andreas Erazo, 18, allegedly stabbed Abbiegail Smith Wednesday night. The girl’s body was found Thursday morning wrapped in a comforter near the apartment building where she lived in Keansburg.

“You killed my daughter, my one and only daughter,” the mom screamed.
