The murder of Diana Miller took place on July 21, 2006, when she and her husband James were robbed at gunpoint by three men in their family home in The Villages, Florida.

The group entered a mall where the men used Sheila to withdraw cash from the family's personal bank accounts from several ATMs.

Just prior to the July 2006 murder, Sheila had been involved in a car accident, which had caused damage to her knee, pelvis, and toe, resulting in her moving back in with her parents at their family home in The Villages.

[4] On July 21, 2006, Sheila received a phone call from her former drug dealer, Renaldo Devon McGirth, whom she only knew as "Pooney."

[6] The men drove to Ocala, Florida where they forced Sheila into a mall and made her withdraw cash from ATMs with bank cards the trio had stolen from the family house.

The Marion County Sheriff's Office had received 911 calls from James Miller informing them his wife had been shot and that his daughter had been kidnapped.

The chase finally ended when deputies used stop sticks, which blew out the tires and eventually caused the van they were in to flip several times.

[7] Both James and Sheila survived the incident, but Diana died in hospital as a result of the gunshot wound to the back of the head inflicted by McGirth.

Houston agreed to testify against his two accomplices in exchange for a lighter sentence of twenty-five to forty years in prison as part of a plea agreement.
