WOODBURY, N.J. (AP) — A defense lawyer says a 15-year-old New Jersey girl charged with setting her family home ablaze and trying to kill its occupants will be detained while she undergoes a mental health evaluation.

Lawyer Richard Josselson spoke after a juvenile detention hearing Tuesday in Gloucester County. He says the girl is a good student who has never been in trouble before. He describes her as "very distraught (and) very upset about what happened."

Relatives at the courthouse say the girl had spent the past school year with her father in Pennsauken before returning last week to her mother and stepfather's Clayton home. That's where the fire erupted early Saturday.

Six people were injured, including the girl. Her mother has been released from a burn center.
