Killed woman's fiance heartbroken

The fiance of a woman killed in a suburban Victorian street says he would do anything to have her back in his arms.

Mark Lofts paid tribute to Rachel Tyquin on social media just days after her body was found on a Sunbury nature strip.

The 44-year-old had been fatally stabbed to the neck, according to police.

"You will be in my head and heart forever babe and I miss you terribly! Would give anything to have you back in my arms," Mr Lofts posted.

"There is an enormous hole in my heart now and I don't think it could ever be filled, you just had so much passion for everything you did and I will miss that every day for the rest of my life."

A 53-year-old woman is expected to face Melbourne Magistrates Court on Monday charged with Ms Tyquin's murder.
