(CNN) -- The bodies of a man and a girl were found inside a vehicle belonging to a suspect in an Amber Alert case, authorities said. Authorities believe 2-year-old Madeline Samaan-Fay was abducted by her father, Mourad "Moni" Samaan. An Amber Alert was issued Friday for Madeline, who was last seen a week ago in Sacramento. In a written statement, the FBI in Sacramento, California, said the bodies were found in Samaan's vehicle Saturday night but did not identify the bodies, saying more information would be released later. The green Toyota 4Runner was found in a remote area of El Dorado County, near Placerville, California, the FBI said.
