The 20-year-old mother of a 15-month-old boy who died after falling three stories from an indoor apartment balcony can't believe he's gone.

Adrianna Spedilari was in the third-floor laundry room at the Cedar Crest Apartments complex while her roommate was watching her son Christopher run up and down the hallway Friday evening. Suddenly, the toddler fell through the railing bars to the ground floor of the building, with a piece of candy lodged in his throat.

The initial emergency call to the building was a baby not breathing, due to a piece of candy blocking his airway. It was only when paramedics arrived that they found the boy had fallen three stories.

A neighbor was able to remove the candy from the boy's throat and begin CPR, getting Christopher breathing again. However, he died after being rushed to the hospital.

"We were walking into his (hospital) room and as soon as we got into the room, Christopher was gone," Spedilari said. "They did everything they could to bring him back, but they couldn't."

Spedilari blames her son's death on the spacing in the railing's wooden bars, which are about 8 inches apart.

"If the bars weren't that far apart, it would have never happened," she said.

Police investigated but said the child's death appears to be an accident.
