Jacksonville, Florida – Abdiel Alexander Badillo-Martinez, a 29-year-old former substitute teacher, was arrested on Tuesday at Southside Estates Elementary School. He faces several serious charges, including possession of a short-barreled gun, rifle, or machine gun, as well as carrying a concealed weapon or firearm on school grounds.
The situation unfolded around 9 a.m. when a school employee reported to the school safety officer that Badillo-Martinez had mentioned he was homeless and stored his firearm in his car because he had no other place for it. The employee, who had previously assisted Badillo-Martinez in unlocking his vehicle on campus, noticed a firearm lying on the floorboard. Following school policy, the employee informed Badillo-Martinez that firearms are prohibited on school property.
After receiving the report, school security personnel and a police sergeant initiated an investigation. During this time, Principal Teresa Dowdell-Brown communicated with parents about the situation, ensuring them that students were evacuated from the building and that movement throughout the school was being restricted.
Upon searching Badillo-Martinez’s vehicle, law enforcement uncovered multiple weapons, a considerable quantity of ammunition, and a knife. Although it was confirmed that Badillo-Martinez was not armed while in the classroom or within the school building, Principal Dowdell-Brown emphasized that having firearms on school property is illegal and poses a serious safety risk.
As a result of this incident, Badillo-Martinez has been permanently banned from working in any Duval County Public School. Records show he had prior misdemeanor charges, including marijuana possession and driving without a license. Such convictions typically disqualify individuals from employment within the school district, particularly if they have two misdemeanor convictions within a five-year period.
Duval County Public Schools employs a substitute teacher provider, ESS, which is responsible for performing background checks on potential hires. These checks include fingerprinting through the Florida Department of Law Enforcement and the FBI to ensure the safety and security of students. In light of the recent incident, there are questions about the hiring protocols and how this individual was allowed to serve in a school environment.
Principal Dowdell-Brown expressed concern regarding the delay in reporting the concern about the weapon and assured the community that this matter is being reviewed by human resources to prevent similar incidents in the future. She reiterated that ensuring the safety and security of students is the top priority for the school.
As investigations continue, the Southside Estates Elementary School community remains shaken by the event. Parents are being informed of ongoing safety measures being put in place to protect their children and to prevent similar situations in the future.
