HARTFORD, Conn. (AP) A 21-year-old Connecticut man has been sentenced to serve 10 years in prison for a PCP-fueled stabbing rampage that seriously injured his cousin and girlfriend in April 2015.

William Brewster was sentenced Wednesday in Hartford Superior Court. He pleaded guilty in March to first-degree assault charges stemming from the attack at his South Windsor home.

Prosecutors say Brewster was smoking PCP with his cousin, 20-year-old Frederick Hazard, when he suddenly began stabbing 22-year-old Dianihtza Rivera-Soto, the mother of his child.

After Hazard came to the woman's aid, prosecutor Rick Rubino says Brewster stabbed him in the face, torso, armpit and shoulders. Hazard was left permanently blind in his right eye.

Attorney Averum Sprecher said Brewster suffers from a mental illness, which spurred the violent outburst along with his drug use.
