“We jumped from the truck and pet the dog,” one of the teenagers wrote in his statement. “After me and my friends got done laughing at the situation, we walked up to the house.”

But before they could knock, Ms. Kelly came out with a gun in her hand.

In her statement, she said she had seen the teenagers approaching and thought they looked suspicious because they did not appear to be selling anything. “All males were African-American,” she added. “And I know this residence to be white.”

She had already noticed that a dog “ran them off” from another home. She said the teenagers did not appear to be knocking on many doors. And she noted that she had been the victim of a home invasion before.

As the boys approached, she grabbed her gun, she wrote. Then she opened her door and asked what they were doing, eventually telling them to get on the ground. “I drew my weapon without my finger on the trigger as I have been previously trained to do,” she wrote.

One of the boys wrote in his statement that during the encounter, he had moved his hand to swat a mosquito. “She told me to stop moving or she will shoot me,” he added.

Another wrote that he had tried to show her the discount cards and had pointed out that two of the boys were wearing their team jerseys. “But as I was saying it, she told us to look down, so I was scared to even talk to her,” he added.

The boys were still on the ground when a police officer arrived. According to the officer’s report, he recognized the boys because he had worked as a resource officer at the high school, and he told Ms. Kelly that they were trying to raise money for the team.
