As police look to identify the burned remains of a suspect believed to be Christopher Dorner, questions still remain on the origins of the San Bernardino cabin fire that ended a six-day manhunt.

Dorner, an ex-LAPD officer suspected of killing four people in an act of revenge against Los Angeles police, was formally charged with one murder last week of a Riverside police officer. A manhunt for Dorner led authorities to Big Bear, where a firefight ensued, followed by a fire at the cabin where the suspect was believed to be holed up. Authorities have yet to identify the body but have reported finding a wallet containing Dorner's California driver's license.

According to the Guardian, the cabin fire likely started as a consequence of tear gas fired by police. An unconfirmed recording of what appears to be police scanners highlights reveals police discussing "going forward with the plan, with, er, with the burn" or "burner." 

What, exactly, "burner" refers to is unclear, but is thought to be slang for tear gas, and possibly "BurnSafe" gas canisters. The Guardian reported the LAPD  is listed as a recent customer of the gas canisters, but not the San Bernardino County sheriff's office.

Spokespersons for the San Bernardino County sheriff's office would not answer any questions about either the fire or Dorner's death, instead holding off for a press conference scheduled Wednesday at 4 p.m.
