A Delaware jury has convicted a pediatrician of waterboarding his companion's daughter by holding the child's head under a faucet.

The jury returned the verdict Thursday against 60-year-old Melvin Morse. He was convicted of one felony, waterboarding in the bathtub, and five misdemeanors, and will be sentenced April 11.

Morse has researched near-death experiences involving children. He denied police claims that he may have been experimenting on the girl.

Defense attorneys argued "waterboarding" was a term jokingly used to describe hair washing that the girl did not like.

Morse was charged with endangerment and assault after the girl ran away in 2012 and told authorities of waterboarding and other abuse.

Morse could face several years in prison.
