Family mourns death of 15-year-old Dunwoody High School student

DUNWOODY, Ga. - The Dunwoody High School community is mourning following the death of a 15-year-old girl on the campus on Monday.

The school sent home a letter to parents and guardians on Monday afternoon. Dunwoody High School Principal Tom Bass wrote that the school was placed on a lockdown during the incident to help restrict movement and allow emergency workers quicker access. 

"At first it was just staff closing the door, and we didn't know if we were supposed to go back to class or not during the lockdown. It was just all the teachers and staff closing doors, and keeping us inside the cafeteria," said sophomore Thomas Tan.

The name of the child was not released, but family members tell FOX 5 the teen's name was Mia.

Palmala Dieguez says her sister wanted to join the military and had a great sense of humor.

"The school called me around 12-1 o’clock to let me know that she was being rushed to the hospital, that she wasn't breathing good. That is what they told me," Dieguez said.

Mia was just 15 years old when she went into cardiac arrest, according to DeKalb County Fire Rescue.

"She always kept to herself. She wasn't a person to always let things out, to speak out, or let anybody in her circle, but you could always tell she was excited for things that she had planned outside of high school," Dieguez said.

An official cause of death has not been determined.
