Detective Senior Sergeant John Clayton said police had not ruled out further charges relating to Reuben’s death.
“We can reassure the community that we are not seeking anyone else in connection with Mr Reuben’s death,” Clayton says.
“We would like to thank every person who called us or came into a station to provide information in relation to this homicide.
“I’d also like to thank our team, who have worked tirelessly throughout this investigation,” Clayton said.
Firefighters found Reuben critically injured inside the house. He died at the scene despite the efforts of first responders to revive him.
About 20 police officers along with fire investigators and ESR scientists were involved in the initial investigation.
