Authorities say a Pittsburgh woman beat and seriously injured her elderly mother — who has dementia — at their home on Mother's Day.

Police say Rose Bynum told them she hoped her mother dies and asked them to kill her mom. She's charged with attempted homicide, aggravated assault and other counts.

Police responded to Bynum's home around 7:30 a.m. Sunday and soon found her mother on her bedroom floor with swelling around her eyes, bruising and serious cuts on her face and neck.

The mother is hospitalized in critical condition. Authorities say she told them Bynum kicked and punched her.

Police say the 54-year-old Bynum told them she had been caring for her mother for 13 years and was tired of it.

It wasn't known Monday if Bynum has retained an attorney.
