Police arrested a young mother on Tuesday on suspicion of smothering her three young children to death, one at a time, in the family's Phoenix home, then propping their bodies on a sofa as if they were napping, authorities and court records said.
Rachel Henry, 22, was booked into the Maricopa County jail on three counts of first-degree murder after admitting she had harmed the children, Phoenix Police Sergeant Mercedes Fortune said.
Court records later showed she was being held in lieu of bail of $3 million.
