captionPIC FROM CATERS NEWS - (PICTURED a collect of Tracey Wilkinson, victim) - THE family of a Good Samaritan wife and her son killed by junkie Aaron Barley have moved back into the home where the rough sleeper slayed them. Peter Wilkinson said going back to live in the house, along with his daughter Lydia, was the most difficult thing I have ever done in my life. His wife Tracey, 50, and 13-year-old son Pierce were killed in the brutal knife attack at the family home in March. SEE CATERS COPY
