More details are emerging about the alleged shooter, a 38-year-old Army staff sergeant of the 3rd Stryker Brigade Combat Team from Joint Base Lewis-McChord in Washington state. He was trained as a sniper and served three tours in Iraq before arriving in Afghanistan late last year. In 2010, he was reportedly treated for traumatic brain injury suffered in a vehicle rollover in Iraq. Afghan lawmakers called on the soldier to be put on trial inside Afghanistan.

Sharifullah Kamawal: “It was a tragic incident for all of us, that these people (Western forces) have repeatedly targeted civilians and killed Afghans in their operation. The Afghan parliament is very sad about this, and we will follow this and will urge the president to put the criminals to trial.”
