A Maricopa County Superior Court commissioner set a $250,000 cash bond against 42-year-old Melissa G. Pacheco. She faces 69 counts of vulnerable adult abuse.
Phoenix police say the arrest stems from an investigation over the past several months of the three facilities owned and operated by Pacheco.
Police say 69 residents, ranging in age from 35 to 89, have been relocated to other licensed care facilities as the investigation continues.
Attempts to reach Pacheco Thursday were unsuccessful.
