Speaking on behalf of the family following the hearing, solicitor Aamer Anwar said: “Calum had a right to life, but his family believe he was treated worse than an animal.
“Left caged, terrified and alone, repeatedly pressing at intercom, screaming for help, coughing up blood.
“He was left to die alone and without dignity for 12 days, without any support from prison officers or healthcare staff from Lothian health board.”
Anwar said the case was a the first successful prosecution in the UK for a Covid-19-related death.
He also said HMP Addiewell, Scotland’s only private prison, was “not fit for purpose” and called for Sodexo’s contract to be cancelled.
His mother Jennifer, a former nurse, said: “Knowing how my boy must have suffered in his cell for 12 days, it is something that will haunt me for the rest of my life.
“He was not just a prisoner. He was my son, a brother, an uncle, and a nephew. He was loved, he mattered.
Inglis’s sister, Frances Marr, said the family would continue to push for accountability for the individuals involved in her brother’s death at a Fatal Accident Inquiry.
NHS Lothian’s medical director Dr Tracey Gillies apologised “unreservedly” to Inglis’s family for the failings in his care.
She said: “NHS Lothian conducted a review following his death to ensure to ensure that lessons were learned and to prevent a repeat of similar circumstances.
“Since then, robust actions, for both NHS Lothian and SPS staff, have been implemented to improve standards of patient safety and care, including the adoption of welfare checks and associated procedures.”
The case is due back at Edinburgh Sheriff Court for sentencing on 17 December.
