A neighbour, Jocelyn Atienza, tells me it is "sad and tragic" news.

"I found out when police came here and we heard the ambulance came earlier around 08:00."

She said a family lived at the house but she only knew them in passing as their children went to school together.

"I only met them sometimes in the street because my son and her kids go to the same school, so we met sometimes in school or in the street and said 'hello'."

She added it was a good community, which would be "shaken up" by the news.

Ms Blundell said she was "still in shock" herself after hearing the news.

“It’s tragic. You don’t expect that on such a close knit community.

“Our community is lovely and always there for each other. We are very close and obviously still in shock,” she said.

She said: "It's quite serious and the whole estate are worrying.

"I was quite shocked - Queen's Hills is quite a quiet estate, not a lot happening and going on around here.

"It's just very scary because it could be someone you know or someone you’ve walked past or maybe someone your friends know.
