An investigation is continuing after an 11-year-old girl with Down syndrome wandered away from her Riverview school and was found dead in a pond several hours later.

Jennifer Caballero, known as Jenny to her friends and family, was last seen at 1 p.m. Monday walking away from Rogers Middle School in Riverview. The girl managed to walk away from her PE class, even though the class of 20 students had six teacher’s aides.

By late Monday afternoon, her body was found in a pond located a couple hundred yards away from the school and surrounded by a four-foot chain link fence.

Officials are trying to determine how the girl managed to leave the class unnoticed and how she ended up in the pond.

"I think that is a question that obviously we have to get answers to and that's exactly what we're going to be doing,” said Hillsborough County Schools Superintendent MaryEllen Elia. "Obviously, this is something that we feel terrible over as a school district. I, as a superintendent, and the staff here, we cannot do anything to change what occurred but we have to do a full investigation so we can all understand this."

“That is certainly a possibility,” said Hillsborough County Schools spokesperson Linda Cobb, on the chance someone may be fired. “We are waiting to see what the outcome of the investigation is, and then we will take action based on that.”

Hillsborough County Sheriff David Gee said his office is working to determine what happened from the time Caballero left school until she was in the pond and if anyone may have seen her in between.

Caballero's family told investigators the girl may have been capable of climbing the fence that blocked off the pond. So far, the sheriff's office is not officially calling the death a drowning.

Next door neighbor and family friend Heather Boffo, who has been with the family since the tragedy happened, said there's a lot of anger and unanswered questions.

“They just don't understand why. They thought their child was safe and secure. And they don't understand why this had to happen,” she said.

Boffo said she will miss hearing the little girl laughing wildly at cartoons every day and seeing her waiting in her mother's arms at the bus stop.

“She'd just hold her up, she was happy; all you see are little pigtails going back and forth. Just laughing and giggling waiting for the bus to come,” she said.

Grief counselors were on campus Tuesday to talk to students.

A prayer service was held for Jenny at the family’s church, Iglesia de Dios, Tuesday night.
