A Burlington County woman charged with burning her newborn infant to death on Friday allegedly doused the baby with flammable liquid before setting her ablaze, according to reports from police released by the prosecutor's office.

Hyphernkemberly Dorvilier, 22, of the 200 block of Rutgers Avenue in Pemberton Township, is charged with murder in the alleged incident that happened at 11:15 p.m. Jan. 16 on Simonton Road.

Prosecutors say Dorvilier doused the female newborn, who had been wrapped in towels and papers, in the flammable spray lubricant WD-40 before lighting her on fire.

When confronted by concerned neighborhood residents, authorities say Dorvilier claimed she was burning feces that her dog had left in her vehicle that was parked nearby.

Those resident detained Dorvilier and contacted police after she attempted to flee after putting out the flames with a bottle of water, authorities say, and the baby began crying.

Prosecutors say officers responding to the scene detained Dorvilier and recovered a can of WD-40 and a lighter in her jacket pocket.

Upon placing the baby that had been on the ground in a police cruiser, officers unwrapped the smoldering towels and paper and discovered that the child still had the umbilical cord and placenta attached, according to prosecutors.

The unnamed baby was airlifted to St. Christopher's Hospital in Philadelphia where she died about two hours later, prosecutors say.

Dorvilier was transported to Lourdes Emergency Department at Deborah Hospital where officers observed her bleeding or "spotting" on a hospital gurney awaiting checkup by a doctor, according to prosecutors.

Authorities say officers responding to her Rutgers Avenue residence discovered a blood trail from the driveway to an exterior door.

Police reportedly made contact with Dorvilier's mother and sister at the residence, who were unaware the suspect was injured or had given birth, according to authorities.

Police reportedly observed blood in the downstairs portion of the split-level home, finding blood and a bloody rag in that bathroom.

Dorvilier has been detained in Burlington County Corrections and Work Release Center on $500,000 bail — with no option to post 10 percent — since the alleged incident, prosecutors say.

Deputy First Assistant Prosecutor Jim Ronca requested that Dorvilier's release upon posting bail also be contingent on a psychiatric evaluation.

Superior Court Judge Philip E. Haines agreed with prosecutors' call for evaluation and a review of that evaluation by the court, in addition to the $500,000 bail.

The charges are "very serious, in the high range of serious ... without a doubt," said Haines in court on Tuesday.

Dorvilier, who appeared in court through video conferencing while in detention, responded by saying "yes, your honor" when asked is she understood the charges against her.

She also indicated that she believed she would be retaining private legal counsel.

Dorvilier's loved ones on hand for the proceedings declined to comment to members of the media outside the courtroom.
