RAMSEY, Minn. (AP) — Authorities say a small plane crash on the Mississippi River north of the Twin Cities killed a Princeton couple.

The Anoka County Sheriff's Office says the plane struck a set of power lines and went down into the water near Ramsey around 5:30 p.m. Friday.

The sheriff's office says the body of 48-year-old Jill Rygwall was found in the river shortly after the crash. The body of her husband, whose name has not been released, is believed to be in the underwater wreckage.

Authorities say the plane took off from the Princeton airport. Witnesses reported that the plane was flying at or below the tree tops before the crash.

A salvage crew was working to pull the single-engine Cessna from the river.

RAMSEY, Minn. (AP) — Authorities say at least one person died when a small plane crashed into the Mississippi River near Ramsey, north of the Twin Cities.

The Anoka County Sheriff's Office says the plane struck a set of power lines and went down into the water around 5:30 p.m. Friday. Authorities do not know how many people were aboard the plane.

The sheriff's office says a woman was pulled from the water by witnesses. She was pronounced dead at the scene. Her name has not been released.

Authorities say dive teams will be on scene Saturday to try and find the aircraft. The recovery efforts are being hampered by high water levels and rapid current on the river.

Officials have not determined where the plane's departure point or destination.
