Thousands of dead prawns have washed up on Chile’s coastline leaving authorities confused about what could have killed them.

“What we are doing today is compiling the most evidence possible to determine if we are facing some kind of environmental crime,” a spokesman said.
This is dramatic. There are other species washed in with the orange-pink tide of large shrimp. A release of pollution or even just a natural occurrence of an inhospitable environmental condition (such as low oxygen), could be the cause. It is being investigated.
