Adam Kostewicz murder

On April 15, 2006, Adam Kostewicz was found murdered in his home in the 16600 block of South 30th St., Ahwatukee Foothills, AZ.  The night of the murder, he told his wife that he wanted a divorce so he could marry his mistress.  His wife, Grace Pianka, was found guilty of the murder and sentenced to 22 years.  Oddly, the mistress never told her husband that she wanted a divorce even though she found the body of Adam.  The mistress also never showed at the trial.

 The newspapers claim that the murder occurred in the 16600 block of South 30th St. but a house in those numbers does not appear to exist on Google maps.  The precise location needs to be found.
