Agency had history with stowaway, 9

MINNEAPOLIS — A 9-year-old boy who evaded airport security and stowed away on a flight from Minneapolis to Las Vegas has also stolen a car and sneaked into a water park, and he is known to child protection investigators, according to a confidential county government memo.

In the e-mail obtained by the (Minneapolis) Star Tribune, Janine Moore, area director of the Hennepin County Human Services and Public Health Department, said staffers have conducted four assessments of the boy’s family since December and that he is a ‘‘challenging’’ child.

‘‘The reports have been inconsistent and there have been no injuries to the child; however, there is a pattern of behavior,’’ she wrote in the e-mail to county administrators and commissioners marked ‘‘private data.’’

Moore said she could not comment when reached on Tuesday. ‘‘That information went out without my authorization, so there’s nothing more I can share with you about that memo,’’ she said.

Hennepin County spokeswoman Carolyn Marinan said the memo is considered private under state law. She said she could not disclose any other details about the county’s involvement except to say the boy is safe.

The memo did not identify the boy or his family or say where they live, the Star Tribune reported.

The e-mail did say, however, that the boy’s mother works at Minneapolis-St. Paul International Airport, where he sneaked onto the plane without a boarding pass or ID Thursday. The Delta Air Lines flight crew realized midflight that he was not supposed to be there, and Las Vegas authorities took him into custody when the plane landed.

The boy became ‘‘violent’’ and was hospitalized in Las Vegas, where hospital staff reported he eventually calmed down, it said.

Minneapolis airport spokesman Pat Hogan said he got through the security checkpoint at least in part by blending in with another family. According to Moore’s memo, that is also how he sneaked into the water park.

His motivation for the trip remained unconfirmed.

‘‘What he told the police in Las Vegas was that he was going to meet a kid he had met online who shared his interest in video games,’’ Hogan said. ‘‘His mother also said they didn’t have any family or friends there so I don’t know if that’s true or not, but that’s what he told authorities in Las Vegas.’’
