A 6-year-old girl died Tuesday morning at Children's Hospital in St. Paul in an apparent drowning at a Highland Park apartment building, officials said Tuesday.

The building is located in the 1300 block of E. Maynard Drive, near W. 7th Street.

The girl's mother was later taken into custody and no one else is being sought.

Investigators have preliminary information on the victim's identity and are working with the Ramsey County Medical Examiner's Office for confirmation. The medical examiner is also working to determine the cause and manner of death.
