Authorities say the 21-year-old male inmate identified as the “alleged assailant” in the killing of a female corrections officer at an Abilene prison over the weekend allegedly attacked the woman as she entered a storage area near the kitchen.
Texas Department of Criminal Justice officials said Monday that the inmate had been convicted of aggravated sexual assault of a child under the age of 14 and had been in prison since 2011.
The as yet unidentified inmate hasn’t been charged in the death of Mari Johnson at the Robertson Unit in Abilene on Saturday.
The Department’s Inspector General is gathering evidence and will present the case to the Jones County district attorney when the investigation is complete.
