When does being a kid stop? Is it at 18, when teens gain legal rights like voting and privacy? Or at 21, when they can buy alcohol? Maybe at 25, when they can rent a car, or 26, when they lose their parents’ insurance. The brain isn’t fully developed until 25, affecting judgment. Teens process information with the amygdala (emotions), while adults use the prefrontal cortex (rational thinking). This context helps us understand the unsolved case of Codi “Geno” Joyce, who died at a party on 9/27/2015. Despite known suspects, no arrests have been made due to lack of police involvement and silence among friends.
