EDMONTON — The suspect in a shooting that killed an Edmonton police officer and wounded another had been the focus of a lengthy hate crimes investigation.

Edmonton police Chief Rod Knecht says police had evidence going back to February of last year when a family grew increasingly concerned about repeated online hatred and bullying.

Knecht identified the suspect as Norman Walter Raddatz, who was 42, and was known to police, although he did not have an extensive criminal record.

Officers had gone to the man’s home in west Edmonton on Monday night to arrest him when gunfire broke out.

Const. Daniel Woodall, a 35-year-old, eight-year veteran of the force, was killed, and 38-year-old Sgt. Jason Harley was shot in the lower back.

It’s believed Raddatz died in the house as the house went up in flames.
