Neighbours questioned after death of Maggie Watson

Police seize items from neighbours of 4-year-old Maggie Watson, found dead at her Onehunga home last month.

Police seize items from neighbours of 4-year-old Maggie Watson, found dead at her Onehunga home last month.

Police investigating the death of 4-year-old Maggie Watson have seized computers, phones and other items from the little girl's neighbours.

The Herald on Sunday understands at least two neighbours have been questioned and police took a number of items from them.

Maggie was found dead at her Onehunga home in the early hours of Friday, August 7.

Her mother, Evelyn Sen, who is understood to have called police, was treated for superficial injuries and has since been in the care of Auckland District Health Board.

Sen was this week allowed back to the house for a short visit while the house was blessed.

She was there for an hour and a half and accompanied by doctors who have been caring for her, it is understood.

Last month, Maggie's Malaysian-based grandfather told the Herald on Sunday toxicology results from a second autopsy showed traces of chemicals or drugs in the pre-schooler's system.

Clifford Sen said police had told him they were treating the case as a homicide.

But more than seven weeks after the little girl's body was discovered no one has been charged.

Police confirmed Sen had visited the house this week and added: "We can also confirm that a number of search warrants have been executed in relation to this case and a number of items of interest have been seized."

The officer in charge of the homicide investigation, Detective Inspector Hayden Mander, said last month that police had results from a number of tests and examinations.

"Those results, combined with a number of discussions with various experts, lead us to the conclusion that another person or people were involved in Maggie's tragic death."
