TAMPA, Fla. (AP) -- Officials say the father of two boys kidnapped from their grandparents' house recently bought a 25-foot sailboat.
The Hillsborough County Sheriff's Office said Friday that 25-year-old Joshua Michael Hakken recently bought a 24-foot, 1972 Morgan sailboat with a blue hull. The boat's whereabouts is unknown.
A pickup truck owned by Hakken was found abandoned Thursday night in a Madeira Beach parking garage.
Officials are searching for clues to help them find 4-year-old Cole Hakken and his 2-year-old brother Chase.
Authorities say Hakken and the children's mother, 34-year-old Sharyn Patricia Hakken, are prime suspects.
The Hakkens lost custody of the children last year after a drug possession arrest in Louisiana. Authorities say he later tried to take them from a foster home at gunpoint.
