A Canberra man has been found guilty of using a gun to take "lover's revenge" after a woman he met on eHarmony broke off their fling.
An ACT Supreme Court jury took about two-and-a-half hours to find Drew Francis Thompson, 28, guilty of charges of aggravated burglary and unlawful confinement.
Thompson wept when the verdict was read out in court on Monday afternoon.
Thompson will now face sentence for arming himself with a gun, hiding in his former lover's apartment, and holding her captive for three hours.
Acting Justice David Robinson ordered a pre-sentence report be completed for a February sentence hearing.
During the trial, the court heard Thompson met the woman on a dating website and the pair had an intimate relationship for five weeks.
But the woman broke it off, telling the accused he was dull, dumb, and a poor dresser.
Thompson refused to give up on the relationship until the woman publicly berated him at Dickson shops in October.
The Crown alleges a humiliated Thompson then put on latex gloves and took a gun to the woman's apartment.
Crown prosecutor Sara Gul alleged he did it to show her how it felt to have trust betrayed.
The court also heard Thompson allegedly ran when police came to raid his home.
The search uncovered a firearm in his father's gun safe, latex gloves in the garage, and two notes.
He wrote in one note that the woman had stolen "what little happiness I had left", and the other referred to "lover's revenge".
But the defence denied the allegations, arguing an unarmed Thompson went to her home where he spoke with the woman and then left.
Barrister Jack Pappas said there had been no evidence of forced entry into the woman's apartment, there had been no DNA evidence, his client had no access to his father's guns, and the notes had been misinterpreted.
