MIAMI -

A South Florida teen charged with fatally shooting a girl while riding a school bus will remain in a juvenile detention center.

The 15-year-old waived his right to appear in court Wednesday morning. He's not being identified by The Associated Press because of his age.

An arrest report says the minor took a gun from his backpack Tuesday and began displaying it on the bus. He then fired it once, hitting 13-year-old Lourdes Guzman. She died at the hospital.

The boy is charged with manslaughter and carrying a concealed firearm. A Police spokeswoman says "it appears to have been an accident."

The victim's mother said in a statement that Jina, as she was known to her friends and family, was a "fun, loving, helpful, a happy girl."
