A former athletic director from Sebastian River Middle School is facing severe federal consequences following a comprehensive investigation into profound misconduct. On Friday, June 5, a federal judge sentenced 42-year-old Mia Johnson to 10 years in federal prison for her involvement in an inappropriate, long-term relationship with a student.
The deeply troubling case began in 2024 when Indian River County deputies received initial reports regarding the athletic director’s conduct. According to sheriff’s officials, the inappropriate relationship spanned approximately one year. The illicit acts occurred across multiple states during official travel periods with the middle school girls’ basketball team.
Upon receiving the initial complaints, the School District of Indian River County took swift administrative action, immediately removing Johnson from the campus and officially terminating her employment. However, as local detectives executed a search warrant at her residence, Johnson fled the jurisdiction, relocating to Kansas City, Missouri.
Her sudden departure prompted a multi-agency manhunt. Indian River County deputies partnered directly with federal officials from the FBI to track her down. She was ultimately apprehended in Missouri and brought to justice on stringent federal offenses.
Here are the crucial facts stemming from the investigation and subsequent sentencing:
- Federal Charges: Johnson was arrested and convicted of the transportation of a minor with intent to engage in criminal sexual activity.
- Prison Term: The judge handed down a definitive 10-year sentence in a federal penitentiary.
- Supervised Release: Following her incarceration, Johnson will be subjected to 25 years of strict supervised release.
This successful prosecution underscores the unwavering dedication of local and federal law enforcement to safeguarding students within the Treasure Coast region. Indian River County Sheriff Eric Flowers praised the collaborative effort that permanently removed the former educator from the local school system.
“Every child in Indian River County deserves to feel safe at school. Our detectives, working alongside the FBI, made sure this victim was heard and that Johnson was held accountable for her actions. We will never stop fighting to protect our kids.”
Local authorities continue to emphasize that the safety and well-being of every child remains their absolute highest priority. Sheriff’s officials officially commended both their internal detectives, their federal partners at the FBI, and the local school district for their seamless cooperation throughout the expansive multi-state investigation.
