“Our next door neighbours told us what happened.”
“He never bothered anybody and always said hello.”
“The couple were beautiful people.”
“It is still the talk of the street.”

“I felt sorry for him.”
“We were just in shock.”
At the time of the incident, next door neighbour Fay Peacock said: “They were very nice people, great people.”
“When the lady first moved in she brought me a cake as a present.”
“She would always say ‘hello’ in a morning. I am very sad.”
