ASSATA SHAKUR: Born Joanne Chesimard in New York City, Shakur has used multiple birth dates that make her either 56 or 61. Aunt and godmother to slain rapper Tupac Shakur, she was a member of the Black Liberation Army and wanted on several felonies when police stopped her and two accomplices on May 2, 1973, in Clinton, N.J. A state trooper was killed in the ensuing gunfight and another wounded. Serving life in prison, Shakur was busted out by armed friends who took hostages. She surfaced in Cuba four years later and was listed in the Havana phone book, then went underground. U.S. authorities offer $1 million for information leading to her capture.

ROBERTO VESCO: Born Dec. 4, 1935, in Detroit, Vesco fled the U.S. in 1972 when he was wanted on charges of looting $224 million from a Swiss-based mutual stock fund. He was later accused of plotting to pay a kickback to Billy Carter, brother of then President Jimmy Carter, in a Libyan arms deal. He surfaced with his family in Cuba in 1982, living on a boat off the island of Cayo Largo. In 1996, Cuba sentenced him to 13 years in prison for illegally marketing a drug he claimed could cure cancer and AIDS. His business partner, Donald A. Nixon Jr., nephew of late President Richard Nixon, was detained along with Vesco but released. Vesco is believed to have served most of that sentence. Cuban records indicate he died of lung cancer on Nov. 23, 2007, at age 71, and was buried in Havana's Colón Cemetery.

VICTOR MANUEL GERENA: Born June 24, 1958, in New York City, the former bank security guard was accused of robbing an armored car company in Connecticut in 1983, taking two security employees hostage at gunpoint, incapacitating them with an unknown injection and making off with more than $7 million — one of the largest robbery hauls in U.S. history. He reportedly gave much of that money to a radical Puerto Rican independence group. He fled to Mexico, eventually taking a commercial flight to Havana carrying a large sum of money. He has been on the FBI's "Ten Most Wanted" fugitive list for years, with a $1 million bounty on his head.

CHARLIE HILL: The 59-year-old Illinois native and Vietnam veteran belonged to New Afrika, a 1970s revolutionary group that sought to establish a separate black nation in the American southeast. He and accomplices Michael Finney and Ralph Goodwin were stopped on a New Mexico highway in 1971 by a state trooper who died in a gunfight. The three later hijacked a TWA flight from Albuquerque airport to Havana. Goodwin drowned at a beach, and Finney died of cancer. The FBI says Hill is still wanted in New Mexico for air piracy and unlawful flight to avoid prosecution.

NEHANDA ABIODUN: Born Cheri Dalton in 1950 in New York City, Abiodun is among those linked by U.S. authorities to Shakur's escape from prison. She is also wanted for a string of robberies. The Columbia University graduate has lived in Cuba since about 1990 and is a driving force behind the scenes of the Cuban hip-hop movement. In writings attributed to her on the Internet, Abiodun claims she still hopes to foment a socialist revolution in the United States.
