A NSW jury was left with no doubt he was the hitman who shot her at her front door in June, 2021.
Mrs Klimovitch's family, who packed one side of Newcastle Supreme Court on Wednesday morning, exploded with emotion as the verdict was read while Hawkins shook his head.
Mrs Klimovitch was the victim of a "targeted" and "premeditated" killing and was shot once in the chest at close range with a shotgun in Queen Street about 8pm on June 9, 2021.
Hawkins, 48, had spent the last three weeks on trial in Newcastle Supreme Court accused of being the man who executed Mrs Klimovitch and did the bidding of her former son-in-law, Stuart Campbell, who had organised the killing over an ugly dispute with the 61-year-old swimming teacher.
Hawkins becomes the second man convicted over the shooting, with 65-year-old former Nomads bikie Stephen John Garland last month found guilty of manslaughter.
Campbell, a drug dealer who had the motive and organised the other two men to help kill Mrs Klimovitch, was charged with murder but died before facing trial.
