The mother of a man accused of murder in the Florida panhandle is now also behind bars after police discovered text messages allegedly showing her help plan the shooting death of a woman working inside The Home Depot.

Keith Agee, 20, was arrested by the Escambia County Sheriff’s Office Friday afternoon in connection with the deadly shooting of 18-year-old Brooklyn Sims hours earlier at the home improvement retailer on Davis Highway in Pensacola. Police did not share the relationship between Agee and Sims, but Pensacola news outlet WEAR said the two have a 2-year-old daughter together.

The sheriff’s office revealed Monday night that Agee’s 50-year-old mother, Sheila, was involved in planning the targeted attack.

“According to text messages, it’s clear that Keith Agee’s mother, Sheila Agee, knew and participated in the plan to kill Brooklyn Sims. Additionally, text messages between mother and son highlight the mother’s involvement in helping locate the victim,” the ECSO wrote on Facebook.
