53-year-old Marc Karun has been charged with murder with special circumstances and kidnapping for the death of 11-year-old Kathleen Flynn.
The Stetson man was arrested at his home late last week and extradited to Connecticut to face the charges.
Flynn was raped and murdered while walking home from school.
The case has haunted the community for decades.
Karun would've been about 20 years old when Flynn disappeared back on September 23, 1986.
