A post-mortem CT scan confirmed that Eli died of a traumatic head injury, The Mirror reported.

An inquest is underway in Preston Coroners’ Court into the death, with area coroner Kate Bisset confirming the police investigation had concluded.

She said there was “no reason to suspect there was any suspicious circumstances or third-party involvement at the time”.

The case will be mentioned in the coroner’s court on October 9, where it will be determined if any further proceedings will be required.

Rossendale and Darwen MP Andy MacNae spoke about the tragedy during Prime Minister’s Questions on Wednesday.

“Last week four-year-old Eli Testa was killed in Rawtenstall Cemetery when a memorial stone fell on him. All of Rossendale was shocked by this tragedy so I hope the Prime Minister will join me in offering our deepest condolences to Eli’s parents and family,” Mr MacNae said.

In response, Prime Minister Keir Starmer said “can I extend my deepest condolences to Eli’s friends and family”.

The Health and Safety Executive, UK’s national regulator for workplace health and safety, have been notified of the situation.

An outpouring of tributes from locals have been flowing for Eli and his family.

A GoFundMe has been set up by Eli’s great aunt, Donna Miller, to cover his funeral costs and to assist his parents to care for their other two children.

“All donations no matter how small will help this young family massively and help them deal with this unexpected tragedy,” Ms Miller wrote.
