According to the criminal complaint, Thoresen struck Haiman with a baseball bat, stabbed and decapitated him after Kayleen Danielle Greniger accused Haiman of raping her.

On June 26, Haiman’s remains were discovered in the Ball Club area, west of Deer River.

Thoresen was charged with second-degree murder, and Greniger was charged with being an accomplice after the fact following Haiman’s death.

This week, the Itasca County Attorney’s Office reported Greniger’s 20-year-old brother Joeseph Allen Greniger, from Grand Rapids, was accused of trying to intimidate a potential witness in the case from “snitching” on his sister.

The complaint says Joeseph Greniger sent the witness a Facebook message and called him, saying “You know what’s coming.”

After talking with police, Joeseph Greniger admitted to threatening the witness.

He is now charged with felony first-degree tampering with a witness, which carries a maximum penalty of five years in prison and a $10,000 fine.
