Alleged Serial Stowaway Marilyn Hartman Arrested for 3rd Time This Month

— -- Repeat stowaway Marilyn Hartman was arrested today at Phoenix Sky Harbor International Airport on a criminal trespass charge, according to police.

It was the third time the 62-year-old, who has a history of trying to board planes without a ticket, has been arrested this month.

Airport employees recognized Hartman loitering today around 11:30 a.m. in terminal 4 near the baggage claim area, according to Phoenix police, who said she was not in possession of a ticket.

The arrest came after Hartman was caught on Aug. 14 trying to enter a Sky Harbor security checkpoint without a ticket. Hartman was let go with a warning at the time and was removed from airport property, police said.

Phoenix police said they were requesting Hartman undergo a mental health evaluation.

Hartman was arrested earlier this month on a misdemeanor trespassing charge after she flew on a Southwest Airlines flight from San Jose to Los Angeles without a ticket, authorities said.

Several days after she was released from police custody, Hartman was seen scouting terminals for about an hour at Los Angeles International Airport, according to airport police. She was arrested and charged with violating the terms of her probation, which included staying out of airports unless she had a ticket to fly.

Hartman was released from a Los Angeles jail earlier this month because of overcrowding, according to ABC News' Los Angeles station KABC.

While she has an extensive history of trying to board planes, Hartman's arrest earlier this month was the first time she successfully was able to fly without a ticket, authorities said.
