TEMPE - The body of an Arizona State University student was found handcuffed and beaten in the bathtub of her boyfriend's Tempe apartment, and he's accused of killing her, authorities said Wednesday.
Luis Soltero, 22, was being held on suspicion of first-degree premeditated murder, with bail set at $1 million, according to Tempe police.
Officers said Soltero walked into a Tempe police substation Tuesday morning, told officers his girlfriend was dead and gave them her Minnesota driver's license.
Police went to the apartment near the ASU campus and found the body of 19-year-old Rebecca Kasper in the bathtub. The body already was in a state of decomposition and was sprinkled with coffee grounds and baking soda, according to court documents released Wednesday. Police said Kasper had injuries to her head and face, and a dumbbell covered in blood was found nearby.
Police said they learned that Soltero and Kasper, a junior majoring in marketing, had recently broken off a relationship but were still seeing each other. A note listing the "pros" and "cons" of "breaking up with Becky" was found in the apartment, they said. Another note found wedged in the bathroom door reportedly stated that Kasper was killed Saturday.
Neighbors told police the couple frequently argued, and the leasing office said a front door had to be replaced after it was damaged during an argument.
After telling police where they could find Kasper, Soltero also said he had been sitting in a car for 12 hours with the engine running. He was taken to a hospital to check for carbon monoxide poisoning, later released and booked into jail.
