The Pinal County Sheriff's Office is investigating the death of a 6-month-old boy, according to a news release from PCSO.
Deputies say on Friday they responded to a residence at 24 East Paso Fino Way in San Tan Valley for a report that a 6-month-old boy was not breathing.
Sheriff Paul Babeu says that when deputies arrived on scene they found a caregiver performing CPR on the child.
As deputies took over CPR, they found that the baby was "cold to the touch and obviously deceased."
Babeu says that the caregiver found the boy in a crib in an upstairs bedroom about 90 minutes after putting him in the crib for a nap.
Babeu says the boy had no obvious signs of trauma and the medical examiner's office is conducting an investigation into the cause and manner of death of the boy.
Deputies spoke to the 62-year-old caregiver and she said she was running a day care business out of her home.
The caregiver told deputies she put the baby in a crib to nap and 90 minutes later when she went to check on him she discovered him not breathing.
The caregiver told deputies she did not report any medical concerns before putting the baby in the crib.
Deputies say they had noted the home appeared to be under renovation with exposed wood, nails and "dirty floors."
