Bert Franklin, of Tulsa, is in the Tulsa County jail awaiting transfer to Oklahoma County. 

A dentist who is accused of killing a toddler with a blow to the head, was leading a double life, according to court documents.

Bert Franklin, 35, lives with his wife and four children in a $1.3 million home in Tulsa.

He had a yearlong affair with the Oklahoma City woman whose 19-month-old boy was killed.

Oklahoma City police Detective Andrea Motley said in an arrest warrant for first-degree murder that neither woman knew of the other.

The girlfriend said she had been extremely concerned because Franklin had begun to exhibit “controlling behavior,” Motley said. The girlfriend also told the detective that Franklin hated the boy's father and had threatened to kill the man, “skin him in Bricktown” and cut off a body part.

Franklin, who has practiced dentistry in Tulsa for eight years, is in the Tulsa County jail, without bail, awaiting transfer to Oklahoma County.

The doctor who treated 19-month-old Lincoln Von Henry Lewis at Mercy Hospital Oklahoma called police Sunday to report injuries consistent with abuse.

Lincoln's head had pinpoints of blood in the skin near the right rear of his skull, likely the location of impact. He had hemorrhaging in both eyes and severe swelling and trauma to his brain, the warrant states.

The boy died Monday afternoon at a Tulsa hospital. 

The “fracture demonstrated a high degree of force to cross multiple suture lines through multiple bones.” A second skull fracture on the side of the boy's head was revealed during the autopsy, the warrant states.

The boy's mother said Lincoln and Franklin were alone in the downstairs living room of her home in Oklahoma City when she heard a loud “thud.” Franklin said the noise was made by throwing a small ball to a puppy.

The detective said Franklin's story is inconsistent with the noise the boy's mother heard. 

“He was the sole care provider for the time frame prior to the boy being symptomatic,” she said in the warrant.

The boy's mother had surveillance equipment in the home. Police seized an external hard drive from that system.
