CLOQUET- A week ago, the Bureau of Criminal Apprehension was sifting through dirt just 24 hours after Cristyna Watson's body was found on the Fond du Lac Reservation.
Now, four suspects are connected to her death.
One of them is Michael Siewert, 22, who was officially charged Thursday with second-degree murder.
The criminal complaint states he did it because he needed drug money and planned to steal her car.
Siewart's girlfriend, Alyssa Peterson, 24, and another man, Clifford Thompson, 53, have also been charged for their alleged involvement.
They got one count of aiding an offender for being an accomplice after the fact, which essentially means they allegedly helped Siewert cover up the body and evidence.
A fourth suspect is an underage male who police have not identified.
