Neighbours of the tragic Boots family have told how they heard the father's heart-rending screams after he found his two babies dead.

Jeff Boots, 34, returned home from work on Wednesday night to find the bodies of his two children Lily Skye, 14-months, and his as yet unnamed 10-week old son, in the family home.

His wife Felicia is today still being interviewed by detectives on suspicion of murder after allegedly smothering her children and attempting to slash her wrists at their new £1.2million home, in Killarney Road, Wandsworth.

A neighbour recalled the agonising moment when she saw the Mr Boots cradling the tots in his arms and sobbing uncontrollably as the reality of what happened began to sink in.

She said she heard the Canadian investment banker, repeatedly crying the words: "My beautiful daughter, my lovely son, they've gone, no, they've gone. Somebody help me, please."

The mother-of-two, said: "It was awful. I could hear the father screaming through the wall. Then he kept repeating 'they have gone, they have gone'.

"I listened out for the sound of ¬children’s voices but none came and he just carried on crying. It was just so upsetting."

Oliver Jones, who lives opposite, said he saw Mr Boots outside his house.

He said: "He was very upset and sobbing and crying. He was beyond words. It’s very tragic especially when you think that these are people who look like you and me.

"Later on I saw the wife come out with a police officer. She was very subdued."

Neighbours saw Felicia being put into a police car by an officer with an arm around her at about 10.30pm that night.

The family moved to Killarney Road just two weeks ago after living in a two-bedroom penthouse apartment in nearby Phoenix Way for the last five years.

The current occupier, who did not want to named, said: "It is horrendous, just awful. I met them both when I first saw this flat.

"I think I remember the wife saying she was so happy to have moved house because it meant more space.

"She said she had been run off her feet because she had a newborn baby. They both seemed very sweet.

"I think they had been there for five years and when we moved in there were some crayon marks on the walls.

"It’s so awful, those children were absolutely lovely."

According to neighbours in Killarney Road, the family were very "normal" and Mr Boots had regularly been seen walking the family dog Labrador called Merlin.

Mrs Boots originally worked as a hair stylist in Canada but soon began creating designer jewellery after setting up an online business called Pink ¬Tangerine when she moved to London. .

On her website she describes her creations as "inspired everyday by life, nature, people, architecture and global adventure"

She goes on to describe herself as "a Canadian-born stylist pursuing a dream and designing from her home-based London studio.

"Felicia Boots, curator of Pink Tangerine, likes to combine various mediums to create unique pieces of jewellery."

One customer wrote on the website's guest book, "This site it fantastic. I love it and all your beautiful pieces. You are so unbelievably talented. Keep up the brilliant work."

Forensic science officers were last night at the scene of the deaths while detectives carried out house-to-house inquiries.

They took out bags of possessions including an Apple computer, children’s clothing and a series of documents from the house.

Sources said the youngsters did not have any sign of visible injuries. A postmortem examination was due to take place to establish how they died.

One said detectives and forensics officers were working inside the house until the early hours.
