Authorities in Arizona say a 22-year-old woman has been arrested on suspicion of dumping the remains of her newborn baby in an area of an Amazon facility in Phoenix earlier this month.

According to KSAZ, Phoenix police arrested Samantha Vivier following the discovery of a baby girl’s body inside a ladies’ restroom at a distribution center in the southwest part of the city at about 8:30 p.m. on Wednesday.

By the following day, police said they had been able to identify the mother, who was cooperating in the investigation, as reported by KNXV.

The remains were reportedly found in a secured location at the facility and police say an initial examination revealed the girl appeared to have reached full-term size at birth.

There was no immediate indication of her cause of death, though investigators say a forthcoming Maricopa County medical examiner’s report will provide additional details.

Court records did not reveal whether Vivier had retained legal representation as of the latest updates available.

Following her arrest on Tuesday, she was booked into the Fourth Avenue Jail. She is expected to face criminal charges including one count of unlawful disposal of human remains.

Shortly after news of the discovery began to spread, police revealed that the case did not immediately appear to be related to the state’s “Safe Haven” law, which allows parents to leave a baby under 3 days of age at an approved location without fear of criminal repercussions.

The Amazon facility remained in operation as police conducted their investigation and a company spokesperson issued a statement confirming that it would be cooperating with police.
