A jury has found Toronto police Constable James Forcillo guilty of attempted murder in the death of 18-year-old Sammy Yatim.
He was found not guilty of second-degree murder and manslaughter.
The seven women and four men in the jury deliberated for 35 hours over six days.
The Crown argued that Forcillo acted as “a hot head and a bully” when he fired nine shots, hitting Yatim eight times aboard an empty streetcar in July 2013.
The verdict means the jury focused on the second volley of shots that killed Yatim.
The incident sparked outrage and city wide protests.
The defence had argued Forcillo was acting in self defence because he believed Yatim intended to use a small knife in his possession.
No Toronto police officer has ever been convicted of murder while on duty.
