(AP Photo/Jennifer Reynolds, Pool) Prosecutors will call their final witness today in the case against Kimberly Dawn Trenor, the Texas mother accused of beating her 2-year-old daughter to death, the AP reports. The Galveston County medical examiner will testify today as the prosecution finishes presenting evidence that Trenor, 20, with her husband, killed Riley Ann Sawyers in a deadly discipline session and hid her body in Galveston Bay. Trenor’s husband, Royce Clyde Zeigler II, 25, will have a separate trial. Trenor’s defense alleges that it was Zeigler who fatally threw the toddler onto a tile floor. Zeigler confirmed this in a note for a failed suicide attempt but has changed his story since being taken into custody. Trenor faces life in prison if convicted of capital murder.
