A 29-year-old man has been cleared of murder but found guilty of manslaughter over his baby son's death.
Michael MacRae is accused of violently shaking his six-week-old baby, Nathaniel, at his Narrogin home in October 2017.
He was rushed to Narrogin Hospital with catastrophic brain injuries and died about a year later at his mother's Golden Bay home.

MacRae has denied any involvement in his son's fatal injuries and claims he had been set up by Nathaniel's mother.
But, on Thursday, a WA Supreme Court jury found it was MacRae who injured his son, handing down a guilty verdict to a manslaughter charge after an hour of deliberations.
He was acquitted of murder.
MacRae is due to be sentenced in March.
