ST. PAUL — A grand jury in Ramsey County has determined there is no cause to charge a St. Paul officer who fatally shot a man involved in a confrontation with police last summer.

Thirty-six-year-old Guillermo Canas was killed by Officer Joseph Sandquist last August after the man raised a rock and approached police. Officers had been called to a neighborhood after witnesses said the man was damaging vehicles and breaking windows with a pipe.

Canas’ sister-in-law, Marta Lopez, said police should have tried other options to calm him. Lopez says her brother-in-law had been telling family members for months that he kept “seeing people” who would hit him.

The Star Tribune reports the grand jury decided Wednesday the officer’s use of deadly force was appropriate under state law.
