WOODBURY, N.J. — A New Jersey teenager charged with attempted murder and arson after a fire at her family’s house remains in custody pending another court hearing.

The 15-year-old was due in family court in Gloucester County on Monday, but the court appearance was postponed after her detention hearing over the weekend. Her name was withheld because she is a juvenile.

Authorities said the Saturday morning fire was set with gasoline. Most of the damage was contained to the second floor of the single-family house.

The teen and several family members were injured, including two who were taken to a burn center in Pennsylvania with internal burns. One juvenile victim suffered a hip injury when she jumped from the second floor to escape the flames.

The suspect is being held at the Camden County Juvenile Detention Center. The county prosecutor’s office said she suffered burns to her feet.

A woman and another relative, who were primarily responsible for helping get the others out of the house, were taken to a burn center in Upland, Pa.

The woman’s husband and a 9-year-old child were treated for burns to their feet and legs. A 6-year-old child in the home was not injured, according to the prosecutor.

Investigators said smoke alarms woke members of the family. Firefighters were able to put the blaze out quickly.
