PLENTYWOOD, Mont. (AP) — Dive teams were searching a northeastern Montana lake Monday for a 19-year-old man missing and presumed drowned after a weekend boating accident.

Sheridan County Deputy Chelsea Brown says two people had to be rescued after the boat sank in Medicine Lake on Sunday. She says the missing man's 17-year-old sister was "code blue," at the hospital, but she did not know what her outcome was.

Brown says the brother and sister apparently were not wearing life jackets.

The coroner was not available for comment Monday afternoon.
