'Serial Stowaway' Shouldn't Be Free On Monitoring: Sheriff

CHICAGO, IL — A "serial stowaway" arrested last week after slipping past O'Hare International Airport security and onto to London flight shouldn't be allowed free on electronic monitoring, the Cook County Sheriff's Office says. In a letter to the Cook County state's attorney, the law enforcement agency objected to Marilyn Hartman's release on bond so long as she find suitable housing in Cook County, NBC 5 Chicago reports.

Hartman has a history as a commercial airline stowaway, and she was charged with felony theft and misdemeanor criminal trespass for allegedly sneaking on to a British Airways flight to London's Heathrow International Airport, where she was detained by British Customs. According to Chicago police, O'Hare security cameras caught Hartman, 66, passing through airport security without a passport or boarding pass Jan. 15.

She was denied entry to Great Britain and flown back to Chicago on Jan. 18, authorities said. That's when police arrested her at O'Hare.

A judge set her bond at $25,000 with the housing stipulation at a hearing Saturday, according to NBC 5. Hartman had been living in a Waukegan nursing center before she was evicted for not paying $55,000 in back rent, the report added. Just before her arrest, she had been living at a facility in Grayslake.

"She is not an appropriate candidate for electronic monitoring and is in need of intense treatment," the letter from the sheriff's office stated, according to NBC 5.

Hartman has a hearing scheduled for Thursday.

Over the past few years, Hartman has faced charges in similar incidents in Chicago and Jacksonville, Florida, as well as the West Coast. Authorities there accused her of trying to stowaway on flights from San Francisco to Hawaii on six separate occasions in 2014.

The Transportation Security Administration is investigating the current incident, but the agency will not comment about how Hartman has been able to find her way past security so many times, NBC 5 reports.
