California police officers may have deliberately burnt down the mountain cabin where the fugitive killer Christopher Dorner was making his last stand, according to evidence from police scanners.

Footage from the KCal 9 TV station reposted on YouTube includes radio traffic from officers at the scene in the San Bernardino mountains shouting at each other to “burn this motherf*****.”

And a separate recording from police scanners appeared to show a deliberate plan to burn down the cabin, with the order given to “go ahead with the plan with the burners”.

“The burners are deployed and we have a fire,” an officer replies moments later.
