(AP) — Leavenworth police say a man whose body was found last week in the Missouri River was a 38-year-old whose last known address was in St. Joseph, Mo.

Police say the death of Jason Davies is being investigated as a homicide. His body was found last Thursday by Nebraska Game and Park employees who were tracking sturgeon in the river.

Leavenworth Police Chief Pat Kitchens says he doesn’t know if someone had reported Davies missing. Police did not release any details about the possible cause of Davies’ death.

Leavenworth and St. Joseph police departments are working together on the investigation.
