After a statewide search, authorities found Marla D'Andrea and her 7-year-old son on Friday night at the Orlando International Airport.
The Jacksonville Beach Police Department reported the boy was in danger and The Florida Department of Law Enforcement issued a missing child alert about 8:30 p.m. It was canceled about an hour later.
Authorities reported D'Andrea fled with her son Luke Gjelaj in a gray 2015 Hyundai Accent and drove from Jacksonville Beach to Orlando.
D'Andrea was in custody late Friday and was held for questioning in the death of a woman at an apartment in Jacksonville Beach.
