UNIONTOWN, Pa.—A man who got $12.5 million after suing state police for shooting his unarmed 12-year-old son has been arrested for trying to board a flight to Jamaica.

Thirty-nine-year-old Michael Hickenbottom Sr., of Greensburg, was arrested Tuesday at Pittsburgh International Airport. He is on parole for a 2006 conviction for possession with intent to deliver marijuana. He was originally given probation in that case, but later jailed for violating those terms.

A Fayette County judge issued a warrant after parole officials say he tested positive for marijuana. The judge lifted that warrant when Hickenbottom turned himself in Monday, but issued a new one Tuesday when Homeland Security officials alerted parole officials he was leaving the country.

Hickenbottom settled his suit in 2008, after state police appealed a $28 million verdict in the 2001 shooting death of his son, Michael Ellerbe.
