(Victoria, MN)  —  Three people are dead from a small plane crash in Minnesota Saturday night.  The National Transportation Safety Board is now investigating the deaths of Jacob and Sara Mertes as well as Dr. James Edney.  The plane they were in struck a house in Victoria, but no one from the home died.  The NTSB said Sunday that parts of the plane’s tail fell off just before the crash.  A home security video shows the plane crashing into an empty lot and then skidding into the home.  But, a full report isn’t expected until at least a year from now.
