My mother received a phone call from this number. It showed up on her caller id as Maricopa County Jail. She was worried it was me or my younger brother that was calling in an emergency (i.e we got arrested) so she accepted the call.
Good news is neither of her boys are serving time. Bad news is an inmate on the line then asked her if she would make a call for him (because he only was allowed to make one call and misdialed) to his girlfriend Courtney and relay a message to her. Mom (trusting soul that she is) agreed and made the call to 480-516-7577... and left a voice mail.
Then the inmate attempted to call mom back again collect... at this point mom wised up and refused the 2nd collect call.
Total scam going on here...
Beware!
