Case history
In September 1981 in Lewisburg, West Virginia, Davis's infant son, Seth, had suffered massive damage to his brain, which prosecutors believed was caused by an injection of a large amount of insulin. He was later moved to a mental institution where he spent the rest of his life. Several months after the incident with Seth, on 11 March 1982, Davis's three-year-old daughter, Tegan, died of a caffeine pill overdose. Dr. Anne Hooper, who performed the autopsy on the girl, had found hundreds of capsules inside of the digestive tract, where she then concluded that the manner of death was likely a homicide.

Trial
In 1997, Davis was put on trial for the murder of Tegan and the injury to Seth. It was reported that prosecutors believed that Davis suffered from Münchausen syndrome by proxy, which is a condition where an individual would falsify sickness of their children to gain attention and sympathy. Although it was believed that Davis had caused the overdose of her son, she had previously stated that he suffered from Leigh's Syndrome or an unspecified growth hormone deficiency. Apart from this, Dr. Barry Wolfe believed that Tegan had suffered from the same genetic disorder. Tegan had been diagnosed with Reye's Syndrome shortly after her death in 1982, in Marybeth's defense, these details contradicted Dr. Hooper's report that Tegan was murdered. Although these details were present, Davis received a life sentence without the possibility of parole. Seth Davis died on 10 October 2002 at the age of 21, and his death was recorded as a homicide.
After signing a plea deal and giving a one-word confession in 2007, the then 55-year-old Marybeth Davis was released from prison.
