A 15-year-old boy in juvenile detention was charged Wednesday with manslaughter after he allegedly took a gun out of a backpack and showed it to other students during the ride to school.

Investigators said he fired it once in an apparent accident.

Lourdes, known as Jina to her family and friends, was struck by the bullet and later died at a Miami hospital.

"Feels like just yesterday I saw her running around in her Pamper, dancing and modeling for the camera," mother Ady Guzman said. "Times and moments spent with Jina are memories I will cherish and keep in my heart forever."

The boy was also charged with carrying a concealed weapon. He waived his right to appear in court Wednesday morning and will remain in a juvenile detention center. He remains unidentified because of his age.

Police have not released further information about the shooting. Miami-Dade Police spokeswoman Aida Fina-Milan said based on the charges "it appears to have been an accident."

Guzman's 7-year-old sister and seven other children were on the bus but were not harmed. Authorities took the children and the bus driver to a police station to be interviewed.

Guzman attended the charter middle school Palm Glades Preparatory Academy. Her sister went to nearby Summerville Advantage Academy.

The teen suspect attended Somerset Academy, said Lynn Norman-Teck, a spokeswoman for the Florida Consortium of Public Charter Schools.

"The principal walked into every classroom to gauge their energy," she said, adding that teachers were notified that all three schools made grief counselors available to students. "But it was business as usual. The goal is to remain a regular schedule as possible," she said.
