MIAMI (CBSMiami) – The South Florida teen accused of accidentally shooting and killing a girl on a private school bus has been released from jail.

Jordyn Howe, 15, bonded out at 11 a.m.

Howe was taken into custody Wednesday and booked into the Miami-Dade County jail after prosecutors upgraded the charges against him. He had been on house arrest.

He’s expected to face formal charges as an adult of manslaughter, possession of a firearm and possession of a concealed weapon during his arraignment on Jan. 28^th.

Lourdes Guzman-DeJesus, whose nickname was “Jina,” was killed when Jordyn took a .40-caliber pistol out of his backpack on the school bus taking kids to three charter schools in South Miami-Dade. The gun went off and a bullet struck Lourdes in the neck. The shooting took place as the bus was near Southwest 296th Street and 137th Avenue. Lourdes, a student at Palm Glades Preparatory Academy, was shot in front of her 7-year-old sister.

Lourdes’ mother Ady believes the state made the right decision in upgrading the charges.

“That’s what we were fighting for he has to pay for what he did as an adult and it teaches other kids to too, this is what you get for doing things you’re not supposed to,” said Ady DeJesus.
