SANFORD, Fla. -

Seminole County School District leaders are launching a full investigation into allegations that a 4th grade student was allowed to continue on with their school day, even though that student was believed to have had a gun in their backpack.

The allegations came in a letter from Winter Park attorney Jededain Main, who said he was hired by a staff member at Hamilton Elementary School, where the alleged incident happened.

The letter states that on May 9 of this year, a 4th grade student told a behavior specialist at the school they had seen a gun in another 4th grader's backpack. The letter states that after questioning that student, nothing was done until a full day later when the 4th grade student was tracked down, and an unloaded gun was found in the backpack. 

"The biggest concern is that this whole situation was not handled in a way that was safe at all," said Main. 

Main also provided Local 6 with a letter he said was given to staff members thanking them for their "confidentiality in regard to this situation."

The Seminole County School District confirmed a letter was sent to parents on Friday letting them know a weapon was found at the school, but they admitted to Local 6 that they were unaware that another student had reported it the day before.

Main said no action was taken against that 4th grader, and his client wants school leaders to be held accountable for their actions.

The district has launched a full investigation into the incident to determine if action should be taken against school leaders.
