When they arrived, officers found that two women had been stabbed. Both women were taken to an area hospital and are expected to survive.

A third woman, identified as Cheryl Rios, was arrested, police said. She was also taken to an area hospital as a precaution.

Rios is accused of stabbing her mother and her child, according to officials.

Prosecutors said the older woman suffered a puncture wound to her chest while her granddaughter had deep cuts on her arms. The motive is unclear, but police say they found blood everywhere inside the home.

"And they observe that kitchen knife that was described to be wielded by the defendant at the time that she was petting her mother against the table now in the kitchen sink with blood on the knife, and that noticeable bent to the knife as well," said Assistant District Attorney Madison Bush.

Neighbors said it was jarring to see police and ambulances in the area on Wednesday morning.

“It’s really sad, but I think it’s less scary when it’s something within the household. It’s not really like a threat to everybody else, I guess," said Sara Lapery, who lives nearby. "Families are kind of going through a lot right now.”

The defendant’s mother and daughter remain in the hospital. Rios will be back in court next week for a dangerousness hearing.
