A brief, but interesting article from Australia:
|Police scientists were called in to test a large amount of blood which collected in the back of a garbage truck at Camperdown in Sydney's inner-west on Tuesday morning.|
Initial tests on the blood were inconclusive, but tests eventually confirmed it was not human.
Garbage collectors had noticed the blood oozing out the back of their truck about 7am (AEST) and raised the alarm.
It's good to know that people are willing to get involved, and call the authorities, when they see something suspicious. At the same time, it also demonstrates the importance of presumptive and confirmatory tests. Something may look like blood, and may even be blood, but it may not be human blood. So where did this (non-human) blood come from? The police couldn't find any answers:
|In full view of curious local residents, forensic officers spent several hours searching the truck's smelly contents for clues to the source of the blood, but found nothing.|
