Action News Jax learned from an incident report released by investigators new details in the tragic killings of a mother and her four children.
Michael Jones is facing charges for four counts of first-degree murder for the deaths of his two children and two step-children.
He's also facing dozens of years behind bars for killing his wife Casei Jones.
Action News Jax investigator Courtney Cole spent hours digging through the 142-page incident report from the Marion County Sheriff's Office. Cole learned from the report that the murders all stemmed from an argument between Michael and Casei Jones.
According to the Marion County Sheriff's Office, Michael Jones told investigators Casei Jones accused him of cheating.
According to the report, Michael Jones said the argument then escalated into a yelling match, and he told her to leave.
The report says Michael Jones told investigators that Casei Jones then picked up a metal bat and pushed him with it ... he then grabbed it from her and told police he "hit her and kept hitting her."
Michael Jones told police he hit and killed his wife, Casei Jones, with the metal baseball bat, July 10.
Michael Jones said he then put her body in a plastic tote and stored it in the closet at their Summerfield, Florida home, where he told police all five of the murders took place.
