Interviews are continuing and results of blood tests have not come back as the investigation into last week's fatal crash of boats on the Osage River continues.
Osage County Prosecutor Amanda Grellner said Friday she was not sure how long it would be before the testing would be complete.
Alvin T. Blackford, 46, Russellville, and Curtis Libbert, 33, died in the three-boat wreck, which occurred about 11:50 p.m. Sept. 3 at the river's Bonnots Mill access, according to the Missouri Highway Patrol's Water Division.
