Murder charge after Tas escapee's death

A young man has been charged with murder after the body of an escaped prisoner was found outside a Hobart home in an apparent shooting.

Police were called to the house in the northern suburb of Granton about 1.30am on Tuesday following reports of a gunshot.

They discovered the body of Nicholas Aaron Scott, 26, who had escaped custody several hours earlier while being treated at the Royal Hobart Hospital.

Tasmania Police on Wednesday charged 20-year-old Granton man Brock Callum Davey with murder.

He remains in custody after his matter was briefly mentioned in Hobart Magistrates Court. Davey did not enter a plea and will next appear in court on January 20.

A 20-year-old man who was found inside the house with head injuries helped police with inquiries, Detective Inspector Troy Morrisby said on Tuesday.

A police investigation into how Scott escaped custody at the hospital is ongoing, while the Tasmanian Prison Service is conducting its own probe.

Police have said Scott borrowed a phone from an unwitting member of the public at a restaurant after leaving the hospital.

Scott had a lengthy criminal history and was sentenced to jail for three-and-a-half years in February 2021, backdated to 2020, on seven offences including aggravated burglary.

He was granted parole later that year, and it is unclear how he ended up back in custody.

The sentencing judge noted he had an "extensive history" of offending but was no longer drug dependent and was motivated to recreate a relationship with his son.
