Police are looking into reports that the mother of two young girls found dead in a South Florida canal was offering to baptize people in the canal a day earlier.

Lauderhill police Lt. Mike Bigwood identified the sisters during a Wednesday evening news conference as 7-year-old Daysha Hogan and 9-year-old Destiny Hogan. Investigators identified the girls’ mother, Tinessa Hogan, as a possible person of interest. She has been taken into custody, but no criminal charges have been filed.
