Can the county police question a minor without a parents permission if something happened at a school function?

In most cases, yes, the county police can question a minor without parental permission if something happened at a school function. This is because police have the authority to investigate incidents that occur in public places like schools, and minors do not have the same rights as adults when it comes to police questioning. However, it is always recommended for a parent or guardian to be present during questioning for the minor's protection.
