A young office worker put her newborn son into a sealed plastic bag and hid him in a desk drawer after giving birth in a toilet stall at a Redford business, authorities revealed Friday at the woman’s arraignment on murder and child abuse charges.

Kimberly Pappas, 25, of Wyandotte, told investigators that after giving birth, she cut the umbilical cord with cuticle scissors and put the baby the bag, returning to her desk with him, Detective Sgt. Kevin Crittenden of the Redford police department said.

For roughly 15 minutes to a half-hour, the baby was in the bag before firefighters arrived and found him still warm in a desk drawer, he said.

Employees had called Redford Fire Department after discovering blood in the bathroom at the business, Ceva Logistics on the 24400 block of Glendale. Pappas had told them it was a miscarriage, Crittenden said, but the autopsy showed homicide by suffocation.
