Boyfriend Admits to Beating 19-year-old Girlfirend to Death With a Dumbbell

Still don't understand why people still endure abuse in relationships in this century....A 22-year-old Arizona man turned himself in to police this week and admitted to beating his girlfriend, a 19-year-old college student, to death with a dumbbell in their apartment days earlier. The victim has been identified as Arizona State University junior and Minnesota native Rebecca 'Becky' Kasper, whose decomposing body was discovered in the bathtub in the off-campus apartment she shared with Luis Soltero.

Court documents indicate that Becky Kasper's wrists were handcuffed and her ankles were restrained, and there was blood splatter in the tub, on the walls and floor. The rest of the woman's body was beginning to decay. A blood-covered dumbbell, believed to be the murder weapon, was found on the bathroom floor.

Next to the dumbbell, police discovered an unsigned note wedged into the bathroom doors which read in part: 'I did not treat her right. She deserved better but never accepted it. So I had to make the choice for her.' The author of the rambling missive goes on to say: 'She died on 420 not because of drugs, but because a sociopath talked and treated her nice...I don't know where to go from here. Do I kill again, end it with myself or become invisible.'

Neighbors told police that Soltero and Kasper had a stormy relationship and often could be heard screaming at one another. The leasing office recently had to replace the front door in Soltero's apartment after it was damaged during a fight between the couple. The 19-year-old victim's employer told officials she often came to work with bruises on her arms as if someone grabbed her, although she had never reported domestic abuse.
