PHOENIX -- A woman is defending her sister who is accused of beating a Mesa man to death.
Mesa police said Judith Walthers, 20, killed Kevin Worzalla while he slept in his apartment at McDowell and Recker roads.
Her sister was questioned by investigators.
"I already got investigated and everything," she said. "They got all of my information and everything I already knew. He asked me what I knew about my sister's whereabouts and I hadn't seen her in like two months."
Walthers has been seen elsewhere, though, including on a talk show about questionable parenting. She is a former Hooters waitress and has appeared in an adult video.
There's also a variety of mug shots from previous arrests, including for assault, shoplifting and driving without a license.
As for the new murder charge, police said she killed Worzalla, a man she stayed with off and on, then stole a lot of his property.
Police said Worzalla's DNA was found on bloody items located at the crime scene.
"[There was] some blood at the crime scene on some of the items that were used to commit this crime and some of the clothing, sheets, other things like that so we were able to directly tie her to this crime through DNA evidence," said Detective Steve Berry with the Mesa Police Department.
Walthers' sister said she isn't a killer.
"I know my sister, that's all I can say," she said.
Walthers hasn't admitted to the crime, but according to court paperwork she tried to recruit a family member as an accomplice.
She is facing charges including first-degree murder, burglary and theft of means of transportation.
