A Floyd County woman who killed her two children and then herself Wednesday had been diagnosed with terminal cancer, police confirmed for 11Alive News Friday.

Authorities said they learned through interviews that Gina Davis had expressed concerns to friends about the welfare of her children after her death. She was also taking medication for the treatment of depression.

The bodies of Davis and her 12-year-old son, Blake, were found inside a bedroom at their mobile home. Her 7-year-old daughter, Presley, was lying in the bathroom. Law enforcement officials believe the daughter may have run into the bathroom to hide.

“At this point, we’re speculating that the young boy was shot first as he was laying on the master bed and then young girl was shot,” said Floyd County Det. Dan Bickers.

A .38-caliber revolver was found beside Gina Davis. Her boyfriend discovered the bodies when he went looking for the family, police said.
