ST. PETERSBURG, Fla. - Confusion. Fear. Silence.

That's what Broward County emergency dispatchers faced as frantic parents and relatives, citing texts and calls from loved ones inside, reported shots being fired inside Marjory Stoneman Douglas High School on Valentine's Day.

Nearly a dozen of the 81 calls dispatchers received were released by the Broward County Sheriff's Office on Thursday.

"While 911 operators are obtaining information from callers, they are simultaneously updating the dispatchers via the computer aided dispatch system in order to disseminate that data to deputies on scene," the agency said in a statement.

One call was of a man who was next to a woman whose two daughters were hiding inside the school's 1200 building.

"If he shoots, play dead," she told one of her girls.

The sheriff's office said the remaining calls will be released per media request.
