Robert Lee Miller, 43, of Chico agreed Monday to a 12-year prison sentence for a charge of burglary of habitation with intent to commit assault.
Miller was arrested March 17, 2012, after allegedly engaging in a violent struggle with his girlfriend, who was pregnant at the time, and her grandmother.
Miller lived with his girlfriend, Aimee Parr, on property belonging to her grandmother, Susan Younger.
“The grandmother went down to check on her,” said Assistant District Attorney Jay Latham. “(Parr) said he assaulted her, and she was going to call the sheriff. Miller grabs the phone from her hand and throws it, and then he head-butts her.”
Younger then grabbed a gun and threatened Miller with it. At this point, his 6-year-old son drove up amid the action on his four-wheeler. Miller then took the gun from her and struck her in the arm with it.
Parr fled to her grandmother’s house for safety, but Miller broke in after her and proceeded to assault her. When Miller was arrested that day he was charged with assault to cause serious bodily injury, assault causing bodily injury/family violence, interfering with an emergency call, resist arrest or transport and burglary of a habitation with intent to commit another felony.
Miller had two prior convictions in Tarrant County. He was found guilty in September 2004 and again in July 2007, both times for possession of methamphetamine of four to 200 grams.
