MOUNT CLEMENS (AP) – A 20-year-old man charged with murder in the fatal stabbings of his grandfather and uncle in suburban Detroit has been deemed not competent to stand trial.

A psychiatric evaluation of Marcus Kragness determined that he was not mentally capable of assisting his attorney in his own legal defense, The Macomb Daily of Mount Clemens reported. He’s expected to remain in custody at a mental health facility.

The victims were 79-year-old Jerome Pastuszak and 44-year-old Mark Pastuszak. They were found on Aug. 31 at their home in Sterling Heights. Police say Kragness had been living with them for just a few weeks after relocating from North Carolina.

Seventy-one-year-old Sandra Pastuszak, who survived the attack, called police to report that her grandson was out of control.
