Search for witnesses in WA murder case

The unsolved murder of an elderly Perth woman during a suspected home invasion has led detectives to release images of people seen in the area who might have information.

Valeria Fermendjin, 70, was found dead inside her home on Leach Highway in Melville in January.

Police say the people whose images have been gleaned from CCTV and dash cam vision were "simply going about their daily business", but they might have seen something that could help piece together what happened.

Police last month announced a $100,000 reward to help solve Ms Fermendjin's murder.
