Tributes are being paid to 23-year-old Catherine Wells-Burr whose body was found in a burning car near Ilminster on Wednesday morning
The defendants had spent months leaving a false trail for detectives before the murder, creating fake profiles for Miss Wells-Burr on adult websites and sending texts to her phone from a supposed mystery lover.
Business graduate used a number of social networking websites and at first Nowak and Lagwinowicz had attempted to lure the 23-year-old into flirting with other men, by targeting her accounts with suggestive messages.
But their plan was thwarted when Catherine either ignored the messages or replied "I have a boyfriend, leave me alone".
The killers instead launched a number of fake profiles for Miss Wells-Burr to leave a false trail for officers investigating after her death.
After their arrest Anna Lagwinowicz made another attempt to cover her tracks from prison, attempting to send a fake anonymous letter to prosecutors that claimed Rafal Nowak had first tried to hire a hit man to kill her.
When this failed, the letter stated, he decided to murder Miss Wells-Burr instead and plant evidence to point the death squarely at Lagwinowicz's hands.
However her scheme backfired when prosecutors were told by her cell mate about the letter and instead used details contained in the note to compile further evidence for her prosecution.
The family of Catherine Wells-Burr said that they are "devastated by the betrayal" of Rafal Nowak who has been found guilty of her murder.
In a statement her family paid tribute to the. "inspirational, amazing, caring, kind, intelligent young woman."
Leanne, Phil and I are here today because of the cruel, callous, wicked, evil and sickening act of murder against "Our beautiful Catherine."
Catherine was an inspirational, amazing, caring, kind, intelligent young woman, who had her whole life ahead of her with so much potential after gaining her First Class Bachelor of Honours Degree in Business Management at Bath Spa University. We were all very proud of her and the person she had become.
The hatred shown to her has truly shocked us, especially the hatred shown by Rafal Nowak, a man who was meant to have loved her.
His betrayal to our family has devastated us. We treated him like a son and family member.
Anna Lagwinowicz has been devious, manipulative and calculating, her actions to create such sickening false profiles of Catherine demonstrate this and as a result these evil people have made us question our judge of character and trust in people - we trust no-one.
Our world as we knew it has fallen apart. Our lives used to be fun, full of laughter and love. We can see no future without "Our Beautiful Catherine". We are heart broken. No prison sentence will ever be enough. In this country life is not life and we feel it should be.
We are the ones facing the life sentence without her.
