Police have released CCTV images showing Darren Byrne walking his dog, moments after he murdered his wife at their home in Theydon Bois.
Chelmsford Crown Court heard she had been hit on the head by Byrne after finding out he had been having an affair.
The 40-year-old, who had denied the charges against him, had doused his wife's body with white spirit and had turned on the hob before going on an hour-long dog walk.
Returning to find his plan had not worked, he concocted a charade, the jury was told.
He called the emergency services to say his wife was "burned" and told the operator: "The stove was on and the frying pan's on the other side of the room. She's not breathing."
Byrne will be sentenced on Thursday.
