MOUNT HOLLY, N.J. » A woman who set her newborn on fire and left her in the middle of a New Jersey street was sentenced today to 30 years in prison.

Hyphernkemberly Dorvilier pleaded guilty in February to aggravated manslaughter and prosecutors recommended the sentence.

The 23-year-old Pemberton Township woman doused her newborn with accelerant and set her on fire in January 2015, investigators said. The baby had third-degree burns over 60 percent of her body and died two hours after she was flown to a Philadelphia hospital.

Prosecutors say she hid her pregnancy from her mother and sister. Investigators say the baby was found with her umbilical cord and placenta attached.

Police responded to a call about a fire on a road in the township, 30 miles east of Philadelphia. When they arrived, they found a neighbor holding Dorvilier down on the ground and the baby wrapped in a smoldering towel and paper, according to the court documents.

Dorvilier was found with a can of WD-40 and a lighter in her jacket pocket, investigators said.
