POMPANO BEACH, Fla. (AP) — The U.S. Coast Guard found three missing Montana children aboard a boat about 30 miles off the South Florida coastline.

The children — 15-year-old Megan Bryant, 13-year-old Maxwell Bryant and 12-year-old Sesbastian Bryant — were found Tuesday with their father. They had been missing since August when they didn't return to their mother in Belgrade, Mont.

The boat was spotted Tuesday by a Customs and Border Protection aircrew.

Authorities say 44-year-old James Bryant was wanted on a felony warrant after the children weren't returned to their mother after a Florida vacation last summer.

The Broward Sheriff's Office is working to reunite the children with their mother.

James remained in the Broward County Jail Wednesday where he was awaiting extradition to Montana.
