A New Jersey woman has pleaded guilty to setting her newborn baby on fire and abandoning it in a roadway, court documents reveal.

According to the Associated Press, a woman with the unusual name of Hyphernkemberly Dorvilier, was convicted of aggravated manslaughter after previously pleading not guilty to a murder charge.

Police alleged that Dorvilier, a 23-year-old from Pemberton Township, doused the child with WD-40 oil and set it aflame in January of 2015. The child later died from the third degree burns it suffered.

Prosecutors say that the woman had hidden her pregnancy from family members and decided to kill the child immediately after birth to continue the ruse. The body of the burned child was found with its umbilical cord and placenta still attached.

A 911 call from the incident was played in court. Dorvilier can be heard in the background saying, “It’s not mine, it’s not mine… I didn’t do it, I didn’t do it, I didn’t do it.”

Throughout much of her arrest, and initially during her trial, she maintained her claim that the baby was not hers.

Prosecutors have recommended that Dorvilier be sentenced 30 years in prison at her upcoming sentencing phase.
