A court heard how Terri-Marie Palmer, 23, fatally stabbed Damon Searson in the heart after flying into a jealous rage over his social media activity. She then dialled 999 and claimed the stabbing happened accidentally when she threw Damon the blade at the caravan park where they were staying.
"It's a carving knife. We literally only got it today. It's really f****** sharp."
The court had heard how only moments before the killing, she had posted on Facebook: "He p***** me off sitting on Facebook, completely blanking me when I'm talking to him."
She then stabbed Mr Searson, 24, as he checked his messages at their shared caravan in Heysham, Lancs.
Palmer wept as she was convicted of murder and jailed for life at Preston Crown Court last week.
The jury heard the the couple had met at Palmer's hair salon the Costa Del Sol in Lancaster when he went in to get a haircut but they had a stormy on-off relationship.
In one text message Palmer said:
"Crying myself to sleep for the second time this week and it's only Wednesday. Thanks Damon. I'm so angry and hurt I honestly want to f****** stab you."
Just after midnight on August 14 a neighbour at the caravan park heard the couple rowing before Palmer knocked on his door in a state of distress. Searson was found lying on the floor, bleeding heavily from a wound to his chest. On the settee was a bread knife, covered in blood.
Searson was taken to Lancaster Royal Infirmary where he died later. When Palmer was told by police her boyfriend had died, she said: "I didn't mean for it to get him."
