The man who murdered Tara Costigan in 2015 has
at least three months added to his sentence after pleading guilty to bashing
other prisoners in Canberra's jail.
"Careless or inappropriate jail or cell placement has contributed to at
least 20 deaths in NSW prison custody in the past decade, according to a
Crikey
analysis of coronial reports. In three of those cases, inmates were
killed by a cell mate whom prison authorities had previously identified
as dangerous, violent or even homicidal."
