A childhood friend of Lakanwal spoke to the New York Times about the shooting suspect's troubled mind. The friend said the suspect faced mental problems because of what he saw in Afghanistan. "When he saw blood, bodies, and the wounded, he could not tolerate it," the friend said. "It put a lot of pressure on his mind." This shows how tough war scenes can leave heavy marks on a person's brain and heart. Such trauma can make life very hard and affect mental health deeply.
