Authorities said Terrell Cooks, 37, and Seneca Mahan, 43, manufactured fireworks in the garage at a home.
Four people died in an explosion early Friday morning. A 12-year-old also suffered minor injuries.
Cooks and Mahan were arrested and charged with second-degree murder, endangering the welfare of a child, and unlawful possession of a weapon, according to the police.
Police said the suspects admitted to manufacturing fireworks that were more explosive than the state law permitted. They also admitted the victims would help them in manufacturing the fireworks.
A neighbor described witnessing the aftermath as something out of a warzone after the home explosion that resulted in the deaths of four people.
Upon a search authorities also found fireworks and materials for making them in the men’s cars. They were also selling them without being licensed to do so.
The men are being held on a $350,000 cash-only bond.
