Luis Soltero, 22, is accused of killing his girlfriend, Rebecca Kasper, an Arizona State University student.
PHOENIX (CBS5) -
A man charged in the beating death of his girlfriend pleaded not guilty to first-degree, premeditated murder Wednesday morning.
Luis Soltero, 22, will return to court June 24 before Commissioner Lisa VandenBerg.
Soltero is accused of killing Rebecca Kasper, a junior at Arizona State University.
The 19-year-old marketing major's body was found in the bathtub of her Tempe apartment wrapped in a yoga mat and blanket, her head covered with a plastic bag and her face beaten beyond recognition, police said.
Kasper's body was already in a state of decomposition and was sprinkled with coffee grounds and baking soda when it was found, according to court documents. Her wrists were handcuffed and her ankles bound by clear plastic tape.
A dumbbell covered in blood was found near the bath tub and blood was splattered on the walls and floor of the bathroom, according to the documents.
Police said the couple recently broke up and that officers found a note believed written by Soltero on the plusses and minuses of breaking up with Kasper and another note wedged in a door confessing to the killing.
Soltero was being held on $1 million bond.
