A case has been s-l-o-w-l-y unfolding in Australia of a man who murdered a young mother and her toddler, he and his partner then used her identity to steal her benefits over several years, some $100k AUS . The partner successfully impersonated the dead woman at a bank and social services appointments.
I believe that, years later when police closed in, the woman turned over key evidence (a photo he took of the body) in exchange for immunity from prosecution, and therefore this aspect of the murder is no longer being referenced, the prosecution are claiming his motive was a 'love triangle'. I think the motive was her benefits.

Tip of the iceberg it seems Satchie. Hope this isn't O/T but how about this -
Experts estimate that £81million of the £920million that is illegally milked out of the system every year is taken by cheats who do not live in the UK.
Most of the stolen £81million is made up of £47million in pension credit, where families continue claiming for a relative long after they have died.
