The Possession of Maurice Theriault

Maurice “Frenchy” Theriault was a Massachusetts farmer who, according to Ed and Lorraine Warren, became possessed by demonic entities. His case became one of the Warrens’ most dramatic.

The Background

Theriault, a devout Catholic, began experiencing strange phenomena in the mid-1980s. He heard voices, saw visions, and experienced personality changes. His behavior became increasingly erratic and violent.

The Phenomena

According to the Warrens, Theriault exhibited classic possession symptoms: speaking in unknown languages, demonstrating knowledge he shouldn’t have possessed, displaying superhuman strength, and reacting violently to religious objects.

His eyes would reportedly change color. His voice would deepen. He would become a different person entirely.

The Exorcism

Bishop Robert McKenna performed an exorcism on Theriault. The ritual was documented on video. During the proceedings, Theriault allegedly levitated, his face contorted, and he spoke in multiple voices claiming to be demons.

Aftermath

Theriault’s condition improved after the exorcism, though he reportedly experienced periodic relapses. His case was featured in Warren books and lectures.

Assessment

Like many Warren cases, the Theriault possession is controversial. Believers point to the documented exorcism and multiple witnesses. Skeptics note the lack of independent verification and the Warrens’ commercial interests.
