MESA, Ariz. -- Authorities in Mesa have released tapes of the 911 call of a man whose teenage stepson is accused in a killing.
The 16-year-old boy is being held on suspicion of first-degree murder. He's accused of killing his mother, concealment of a dead body and tampering with evidence.
His name is being withheld by The Associated Press because he's a juvenile.
The name of the stepfather is redacted from a 911 recording released Monday by Mesa police.
He says the teen hit him in the head with a frying pan when he came home on Oct. 26.
Police later found the body of 36-year-old Tina Helms Spencer in a backyard shed at the family's property.
Authorities believe Spencer was struck with a frying pan and a hammer and also was choked.
