A former Miami Dade College adjunct math professor is accused of distributing sexually explicit videos of minors on Kik, a messaging app, according to a Miami-Dade Sheriff’s Office arrest affidavit.
Christian Demostenes Constantiny was arrested at 1701 N.W. 87th St. in West Little River on Aug. 27 following an investigation that began in March of 2025.
The 31-year-old faces twelve felony charges of possessing and distributing child sexual abuse material. He pled not guilty to the charges on Aug. 29.
According to the arrest affidavit, police identified Constantiny as the owner of a Kik account named “timeskippe” who was found uploading files and sharing sexually explicit videos of boys and girls between the ages of 3 and 10.
Constantiny was hired at Kendall Campus as a part-time math tutor in February of 2024. In August of 2024 he served as an adjunct math professor, last teaching at the College in the spring 2026 semester.
He was terminated on Aug. 27, according to a College spokesman. That is the same day he was arrested.
“The allegations against the individual in question are deeply disturbing and fundamentally inconsistent with the standards of integrity and professionalism expected by Miami Dade College,” the College said in a statement. “The individual has no current employment or teaching relationship with Miami Dade College.”
This incident is the second arrest of an MDC employee at Kendall Campus in connection to the distribution of child sexual abuse material in the last month. On Aug. 7, Roger Ignacio Sanchez was arrested for sharing videos and images of minors online, following a federal investigation.
