Dentist Sentenced After Blowing up His Office to Gain Insurance Payout

Almost one year ago, an Alabama dentist was captured on surveillance video setting fire to his dental office in Evergreen, triggering an explosion that destroyed the building and slightly injured the dentist.

Last week, Dr. Douglas P. O’Connor was sentenced to 15 years in prison. He will likely serve three years behind bars, the Alabama attorney general said.

“Alabamians put their trust in doctors to do no harm. Dr. O’Connor shattered that trust in the most deliberate way possible. He set fire to his own practice, endangered the lives of those next door and attempted to defraud his insurance company to cover years of reckless spending,” Attorney General Steve Marshall said in a statement.

The explosion and the January 2026 arrest of O’Connor surprised many in the south-central Alabama community. Residents noted that the dental practice, in operation for two decades, was very successful, O’Connor was considered a nice guy and was involved in the community.

But investigators with the state Fire Marshal’s office, the state Department of Insurance and local police spent 10 months probing the blast. Prosecutors said the fire had been deliberately set and that the dentist was heavily in debt.

The dental practice was next door to an Alabama State Troopers’ office, which sustained some $63,000 in damage from the fire and explosion, the AG’s office noted. Surveillance video from nearby offices, which was not made public until recently, showed O’Connor entering the building repeatedly late at night, then striking a match and throwing it inside, causing the explosion, Marshall explained.

Forensic testing later showed gasoline on O’Connor’s clothing, the AG explained. The dentist pleaded guilty Feb. 3. He was allowed to remain out on bond while considering an appeal, according to local news reports.
