Man pleads guilty to shooting WA teenager A PERTH man has pleaded guilty to the shooting death of a teenager 15 months ago. Joseph Giglia pleaded guilty to manslaughter in the WA Supreme Court via video link on Monday over the death of 18-year-old Dale Plaziuk in May last year. Dale's older brother Corey read a statement to reporters outside court, describing it as a "good day" for the family because Giglia had finally admitted responsibility for Dale's death. "It will be a huge relief to our family knowing Dale might finally have some justice being done and that this should now be dealt with before the end of the year," he said.

He said it had been a long and stressful process for the family so far, and they wanted to find out the truth about the circumstances surrounding Dale's death. Dale's mother Michelle, who has three other sons and a daughter, said Dale's death had had a huge impact on the family. "I spend every other day out with Dale cleaning his headstone and asking him to please come home because we all miss him," she said, holding back her tears. Mr Plaziuk said he and his brother wore necklaces commemorating Dale with the inscription: "Forever my brother. Forever my best mate. Giglia will remain in custody at Hakea Prison until his next court appearance on November 5.
