The Milton Police Department is investigating the disappearance of a 22-year-old Milton woman and her child. Family members say they haven’t heard from Michaela Aldridge since Sunday when she left her to go on a walk with her 3-year-old daughter around 7:45 a.m. Around 1:15 p.m. family members got a text from her saying she was staying with a friend. That’s the last time they heard from her. Anyone with information on her whereabouts is asked to call any law enforcement agency.
