The Missouri State Highway Patrol says a 1999 Gator jet boat driven by 28-year-old Daniel Berhorst of Freeburg collided head-on with a 1991 Alumaweld jet boat driven by 44-year-old Norbert Eisterhold, also of Freeburg, at 6:28 p.m. Saturday.

The patrol says the boats were traveling through a narrow passage on the river in Osage County when they crashed.

Two passengers in Eisterhold’s boat, 48-year-old Larry Hennier of Rich Fountain and 25-year-old Mary Talken of Jefferson City, were killed.

Four others, including the two drivers, also were injured in the collision.
