It's a strange story, but it's true. An 87-year-old man was murdered and the accused suspects are his 20-year-old grandson and his 50-year-old daughter-in-law. It gets weird though after the suspects made some paranormal claims about the victim.

Jacob Kempainen and his mother Margaret Kempainen are facing one count each of open murder and conspiracy to commit homicide after they allegedly shot 87-year-old Alvin Kempainen.

The killing happened at the victim's home near Lake Superior in Houghton County, Michigan.

The mother said that her son was the one who shot Alvin Kempainen. Both of them also made bizarre claims about how the shooting took place. They said that they believed that Alvin had already been murdered by malevolent spirits. Jacob then said that the spirits told him that Grandpa had opened up the well behind the house and then the spirits killed him.
