The body of Becky Kasper, a 19-year-old Arizona State student who graduated from Northfield High School in 2011, was found in the bathtub of her boyfriend's apartment Tuesday morning.

Officers made the grisly discovery after Kasper's boyfriend, 22-year-old Luis Soltero, showed up at a Tempe police station and said, "My girlfriend is there and she is dead, and I am not going to tell you anything more without an attorney."

Distraught over what he'd apparently done, Soltero told officers he'd spent the previous 12 hours sitting in his car in a storage space while the engine ran. He was taken to a hospital before being transferred to jail, where he's being held on suspicion of first-degree murder with bail of $1 million.

The Phoenix New Times details what officers discovered when they entered Soltero's apartment:

According to court documents, [Kasper's] body was covered with blankets and a yoga mat, with coffee grounds sprinkled on top. Her head was covered with a plastic bag and other plastic wrapping. Her wrists were handcuffed and blood spatter was in the bathtub, around the bathtub, on the walls, and on the floor.

Kasper was described as "unrecognizable" due to blunt-force trauma to her face and head, and her body was in a state of decomposition. A bloody dumbbell, believed to be the murder weapon, was found on the bathroom floor.

Police found the unsigned note wedged into the bathroom door, with statements such as, "I did not treat her right. She deserved better but never accepted it. So I had to make the choice for her," and "She died on 420 not because of drugs, but because a sociopath talked and treated her nice," as well as, "I don't know where to go from here. Do I kill again, end it with myself or become invisible."

Police say the handwriting on the note appears to be consistent with Soltero's. Another note found in the apartment, also apparently written by Soltero, listed the "pros and cons" of "breaking up with Becky." Indeed, police learned the couple had recently split but were still spending time together.

Investigators spoke to Soltero's neighbors, who said he and Kasper were "consistently engaging in verbal altercations." Meanwhile, Kasper's employer said she would sometimes show up to work with bruises on her arms that looked like grab marks.

As Soltero was being transfered from the hospital back to jail, he asked an officer a grim question, the New Times, citing court documents, reports.

"Do they still have final meals on death row?" Soltero asked. "I was wondering if I can order something from Texas."
