MESA, Ariz. (AP) -- Mesa police say the deaths of a woman and her 12-year-old daughter in their home were apparently a homicide and suicide.
According to police, officers responding to a 911 call went to a home where a man said he'd returned from work Monday and found his wife and daughter dead.
Police identify the mother as 45-year-old Marcia Wentzel and the daughter as 12-year-old Caitlin Wentzel.
Sgt. Tony Landato says the mother and daughter had been suffering from what Landato called "debilitating, long-term medical conditions" and he says two suicide notes were found in the home.
Landato says the Maricopa County Medical Examiner's Office will determine the cause of death but that evidence at the scene suggests possible asphyxiation and prescription drug overdose.
Police say their investigation continues.
