A preliminary examination is under way in Plymouth in the case of two teenagers accused of fatally stabbing an adult acquaintance and mutilating his corpse.
Prosecutors say the teens killed 26-year-old Daniel Sorenson for the thrill of it.
They say the defendants then took a blowtorch to Sorenson's corpse and threw his severed head into a river.
Seventeen-year-old Canton High School senior Jean Pierre Orlewicz and 18-year-old Alexander James Letkemann of Westland face one count each of first-degree premeditated murder, felony murder and mutilation of a corpse.
The murder charges carry mandatory sentences of life in prison. Mutilating a corpse carries a maximum sentence of 10 years.
