Victorian Police have confirmed an number of bullet casings and several axes have been seized from a Glenroy property where Antonio Loguancio was found dead on Sunday.
Loguancio, 40, a convicted sex offender, held police at bay for almost two days. His body was found in a bungalow on the property.
Fairfax media reports fired about 50 shots from a semi-automatic rifle and a double-barrelled shotgun before police moved in yesterday.
Police could not confirm whether the casings were from Loguancio or police.
Officers took photographs at the rear of the property and removed what appears to be burnt pieces of clothing.
Inspector Dean McGowan says officers will doorknock the area seeking information.
"Hopefully we can resolve that part of the process and hand the property back to its rightful owner," he said.
Owner Sam Haddad says he did not know Loguancio.
Mr Haddad says he has owned the investment property for a couple of years, but Loguancio was not his tenant and he did not know about the siege until he was told by police.
The homicide squad is preparing a brief for the coroner and the police ethical standards division will also investigate.
