FLORENCE, Ariz. -- A Casa Grande man has been indicted for the stabbing death of his mother last month and wounding his aunt.
Pinal County prosecutors said 38-year-old Joseph Cain Cecil is facing charges of premeditated first-degree murder, attempted first-degree murder and aggravated assault with a deadly weapon.
Cecil has a Nov. 25 pretrial conference.
County sheriff's officials said 65-year-old Ronna Thomas was found stabbed inside a home on Oct. 4. She later was pronounced dead at a Casa Grande hospital.
The victim's 63-year-old sister was taken to a Phoenix hospital for treatment after Cecil is said to have attacked her along with a neighbor who tried to help the victims.
Authorities said the unidentified neighbor hit Cecil several times with a shovel to stop the attacks.
