An inquest into the death of an Alvaston man who drowned in the Derwent has been opened.
Hayden Marshall was found in the river near Raynesway last week.
This was seven months after he went missing on December 17 last year.
At the time, CCTV footage released by Derbyshire police appeared to show the 28-year-old falling into the river.
Mr Marshall was wearing a checked blue and white shirt, blue jeans and a black leather jacket when he went missing at around 1.15am.
Officers found then found a body further downstream in Alvaston on July 22 this year, seven months after his disappearance, which has since been formally identified as that of Mr Marshall.
He was taken to hospital and given a post-mortem by Dr Rutledge on July 29, which put the cause of death as drowning.
But now an official inquest into the circumstances surrounding that death must take place, as the death was unnatural.
The inquest was opened at Derby Coroners Court by assistant coroner Emma Serrano.
Miss Serrano then adjourned the inquest pending further information, but due to the Covid-19 crisis, a firm date for the next hearing was not set.
Mr Marshall, of Border Crescent, worked as a domestic cleaner during his life.
His mother officially identified his body in hospital.
Following the discovery of Mr Marshall’s body, a Derbyshire police spokesperson said: “We would like to thank everyone who supported the many appeals we shared as part of the investigation to find Hayden.”
