Tampa, Florida -- The mother of a 7-month-old infant who drowned in a bathtub is in jail after police say her negligence led to her baby's death.
Hillsborough Sheriff's deputies say around 4:15 p.m. Sunday, Sierra McMillan put her 7-month-old in the bathtub with the water running. She then left the infant, with the water still running, to answer the door to a solicitor.
While inside, the solicitor told police he heard the water running and the child crying. After a few minutes, the crying had stopped.
The solicitor then said after about 15-20 minutes, McMillan went into the bathroom and turned off the water. When she returned to the living room, the solicitor noticed the front of her shirt was wet. The solicitor stayed in the apartment on Seaford Circle for a few more minutes until McMillan told him to come back another time.
As he was leaving, the solicitor saw deputies and emergency personnel arriving at the apartment. When he saw EMS leave with a baby, he approached deputies and told them what he saw inside.
The sheriff's office says an autopsy revealed the infant's cause of death was a drowning of an unattended child.
During an interview with McMillan, she told investigators she was passed out as she was kneeling to the baby soap from under the sink. When she woke up, she said she found the baby face down in the tub with the water filled halfway up. She said she never left the bathroom to answer the front door.
Based on the autopsy results and the witness account of what happened, deputies arrested McMillan, 22, on Monday and charged her with aggravated manslaughter of a child.
