Bartlesville Police Capt. Jay Hastings confirmed the investigation into Tom White’s death.
White had been reported missing last Tuesday. Hastings says that’s the same day police received a report about the alleged molestation.
The 64-year-old White was the executive director for The Voice of the Martyrs, which says it provides medical supplies, food and clothing to persecuted Christians worldwide.
Police found White’s body at the organization’s Bartlesville headquarters Wednesday.
Authorities say employees discovered a letter in White’s vehicle indicating he was “suicidal or possibly fleeing to avoid investigation.”
The ministry says in a statement that White “appears to have chosen to take his own life.”
