Detroit police arrested McKinnie on Thursday, the same day the body of 46-year-old Sanguenetta Evans was found with many stab wounds.
The girl was treated for stab wounds to the face, neck and chest before being taken to a hospital for treatment.
According to Crime Stoppers, several individuals were involved in a gambling/dice game that led to a fight when Walden stabbed the first person he approached.
Prosecutors say the plan was to kill the girl’s brother, sister and parents so she could run away with her much-older boyfriend.
Police say Sikorski and her boyfriend, 23-year-old Michael Rivera of Detroit, conspired to kill her family members and run away together.
The man allegedly formed the plan with his younger girlfriend to “get rid” of her parents, who were reportedly trying to keep the couple apart.
Officers were called about 12:45 a.m. Friday to the apartment and found that 33-year-old James Arthur Washington had been stabbed multiple times.
“As I went to her, she started slashing me. She said something out of anger like, ‘You won’t mess with me,’” Blige testified.
The state says an inmate used a prison-made weapon to stab a guard multiple times at a prison near Jackson.
The delinquency petition filed in Kent County Circuit Court said the 12-year-old told investigators he’s “bad and always does stupid things.”
