NASHVILLE, Tenn. -- A mother spoke Monday about the fear she experienced last week when a stranger pretending to be a nurse tried to walk away with her infant child.

Because hospital rooms are busy with doctors and nurses coming and going all the time, the child's mother, Michelle Gibson, said she didn't think twice when a woman in hospital scrubs walked in and said she needed to take the baby away for tests.

Maia Renea Warmack was only a day old when police said Adriene Johnson, 24, tried to abduct the infant from her mother's bedside at Metro General Hospital.

"She had a badge on, and so she just told me she that needed to take Maia to go get her temperature taken at the nursery, so I said, 'OK,'" said Gibson.

Police said Johnson walked out of the hospital room, tried to take off Maia's arm band, which triggered an alarm.

"She left the room, and then after that, I heard over the intercom 'Code Pink,' but I really didn't know what that meant or how, or even if, it related to my child," said Gibson. "I have no idea why she chose her. I am so surprised that I just have no idea."

A pediatrician and police officer found Johnson a short time later inside the hospital and immediately returned the child to her mother.

"She's great, very beautiful. She's just a great thing in our life. We love her very much," said Gibson.

Gibson said she later learned that Johnson's hospital badge wasn't the same color as all of the other nurses.

Johnson also removed the baby from the bassinet, which deviated from how other nurses had cared for the child, said Gibson. She said the nurses who staff the hospital would roll Maia away, bassinette and all.

Gibson said she feels sorry for Johnson, who is jailed and charged with kidnapping.
