(KCEN) -- The father of that nine year old who snuck his way on a plane from Minneapolis to Las Vegas is speaking out.
The dad says he has repeatedly tried and failed to get help for his son's behavior problems.
He held a news conference on Wednesday with a sweatshirt wrapped around his face to conceal his identity.
The father says the family thought the boy had gone out to do a household chore last Thursday when he disappeared.
Investigators are trying to figure out how the boy somehow slipped past security and got on a Delta plane.
According to his father, the boy was not in school the day he hopped the flight because he'd been suspended for fighting.
