A homicide investigation has been launched after the death of a woman in her Wellington home earlier this week.

Helen Gregory, 79, was found dead by police at her home at Baroda St, Khandallah, at around 11.50pm on Wednesday, January 24.

While her death was initially being treated as unexplained, Detective Senior Sergeant Tim Leitch said a post mortem completed today showed that Gregory had “died as a result of a violent act”.

“Our thoughts remain with Helen’s family and friends at this difficult time,” he said.

Inquiries have been conducted by police in the Baroda St area over the past several days.

A scene examination also remains ongoing at the address, and police staff are expected to remain there for “another day or two”.

Anyone who saw or spoke to Gregory in the days before her death has been asked to contact police.

“This includes any of her friends or contacts who have not yet been in touch with police,” Leitch said.

Police are also looking to hear from anyone who was on Baroda St on Wednesday and “may have seen any unusual activity” or “anyone they didn’t recognise as a resident in the area”.

“Police believe there is no risk to the community,” a police spokesperson told 1News.
