- A former Milwaukee Public Schools paraprofessional received a deferred plea agreement for slapping a special education student.
- Personnel records show the paraprofessional, Demitrios Visvardis, was accused of slapping another vulnerable student a year earlier.
- Milwaukee Public Schools did not report the first incident to the police, according to department records.
When family members of a special education student voiced displeasure with a deferred plea agreement for former MPS paraprofessional Demitrios Visvardis in February, they were told it was fair given his lack of prior offenses.
Visvardis was charged with battery four months earlier in connection with an incident involving Shrone Dunn, 18, of Riverside High School.
“This ain’t nothing but a slap on the wrist,” Tyrone Dunn, Shrone’s father, said during the plea hearing. “We’re looking for justice.”
Milwaukee County Judge David Borowski assured Dunn of District Attorney Erin Karshen’s ability to fully prosecute based on what was known.
But records obtained by the Journal Sentinel through an open records request raise questions about Visvardis’s history, and how much was known before the plea deal was reached.
Visvardis has no prior criminal record, but documents in his personnel file at Milwaukee Public Schools reference a 2024 accusation that he struck a special education student.
In a December 2025 letter filed after a disciplinary hearing, MPS hearing officer Natalie Fluker said the November 2025 incident involving Shrone Dunn was “the second time in a year that [Visvardis has] been accused of slapping a vulnerable student.”
The letter references findings made by hearing officer Gary Johnson during disciplinary proceedings related to the 2024 incident.
Earlier incident also involved slapping
According to the December letter, another Riverside High School staff member expressed concern to Principal Jeff Lasky after witnessing Visvardis slap an intellectually disabled student on October 10, 2024. As with the incident involving Dunn, review of security footage confirmed the allegations.
Visvardis physically kept the student on a vent near an exit on the first floor of the school building despite the student’s multiple attempts to get up, according to the letter. Describing the footage, Johnson wrote, “The student appears to scream and you turn and slap him on the face. You then exit the hallway.”
Visvardis apologized for the incident, stating it was the worst thing he’d ever done.
Milwaukee Public Schools failed to report prior incident
According to the MPS employee handbook, the district generally follows a progressive discipline model that depends on the behavior and frequency of occurrences.
Johnson found the first incident to be “especially egregious, considering the unnecessary and excessive force” used on Student A and recommended a departure from the progressive discipline model. The departure meant Visvardis would be issued a three-day unpaid suspension and required enrollment in a course in nonviolent crisis intervention.
The school district did not directly respond to questions from the Journal Sentinel about whether the police were notified of the incident in 2024. It also declined to say whether Student A’s parents were informed or what steps were taken to protect the student following the incident.
“The safety of our students is our highest priority,” Stephen Davis, a media relations manager at Milwaukee Public Schools, told the Journal Sentinel in an emailed statement. “We cannot discuss the details of any personnel matter, and the current administration would not be able to speak about how a prior case was addressed in 2024.”
But according to Milwaukee Police Department records, no report associated with Visvardis exists since January 2021 beyond the report on his arrest on November 13, 2025. That’s the day after Riverside cameras captured footage of Visvardis slapping Dunn “with an open hand to the left side of face,” according to police records.
Review hearing scheduled for this week
Visvardis is due back in court on Thursday, June 4.
According to the deferred prosecution agreement obtained by the Journal Sentinel, he will be eligible to seek employment in a “school, group home or any other place of employment where he would interact with other vulnerable people” this month, given successful completion of an anger management treatment program.
Meanwhile, the Dunn Family has filed a lawsuit against the City of Milwaukee, Milwaukee Board of School Directors, and Visvardis.
