Milo (Indoor Fireworks)

Milo is a kid who accidentally shot Ryan in the chest.

History
Milo's mother, Ruby, was washing dishes at her house when she dropped a glass and cut herself on it trying to catch it. She started bleeding profusely and her cries drew the attention of Andy and Ryan, who were nearby. They tended to Ruby and when they learned she couldn't afford an ambulance ride, Ryan called Pruitt to take her to the hospital off the books. Ryan and Andy stayed behind to watch her two children for her. Ryan played good guys and bad guys with her Milo. Later, they were surprised when Milo found a gun in the apartment and pointed it at them as if they were still playing. He then fired the gun, which hit Ryan.

Familial
His mother is raising him and his sibling alone. Their father is not allowed within 100 yards of them and doesn't help support them.
