Officers engaging in a gun battle with a person they believed to be Christopher Dorner in a San Bernadino cabin lobbed incendiary tear gas into the structure where the ex-cop was holed up. The cabin burned, and authorities believe Dorner was burned alive inside it. A body was retrieved; its identity has not been confirmed.
Hoping to end the standoff, law enforcement authorities first lobbed "traditional" tear gas into the cabin. When that did not work, they opted to use CS gas canisters, which are known in law enforcement parlance as incendiary tear gas. These canisters have significantly more chance of starting a fire. This gas can cause humans to have burning eyes and start to feel as if they are being starved for oxygen. It is often used to drive barricaded individuals out.
