The event raised $3500 for Wimmera Base Hospital.

Wimmera Superintendent Graham Kent took the audience through his involvement in the investigation of the Hoddle Street massacre in which seven people were murdered in Clifton Hill in 1987.

Mr Kent refused to name Julian Knight - who is serving seven life sentences for the massacre - at any time during the presentation.

"I prefer to focus on the victims and that includes the people who died, their families and the people who were injured," he said, 

"I think it's more important to recognise them and tell their stories rather than focus on the killer who most people know a bit about already. 

"He's quite prominent in the media and I'd prefer we honour the victims and their families."

Mr Kent said the Blue Ribbon Foundation was an example of a community-based organisation that supported the work of police.

"One of the really great things about it is it raises money for hospital emergency centres," he said.

"It's a great example of a community organisation that benefits communities."

Detective Senior Sergeant Jeff Maher explained the complex investigation that followed the 1995 kidnap and murder of Tuan Anh Le.

The international investigation spanned three continents and uncovered a major heroin trafficking syndicate.

Mr Maher said it was a good chance to give the community an insight into a major homicide investigation.

"Nights like these bring the community and the police a bit closer together and the money raised goes straight to the hospital," he said.

Country Fire Authority state fire investigation co-ordinator Nicole Harvey gave a presentation on fire investigations.
