FBI sources said Chesimard is a domestic terrorist who had murdered a law enforcement official. Chesimard, 65, a fugitive living in Cuba under the name of Assata Shakur, belonged to the Black Liberation Army in 1973. It was then when she had killed the trooper, Werner Foerster, during a traffic stop.
State police sources said Foerster was badly injured in his right arm and abdomen and then killed with his own service weapon on the roadside. Chesimard's handgun was found near Foerster.
Chesimard was convicted four years later but escaped from the prison two years late and spent time in a series of safe houses in New Jersey and Pennsylvania before fleeing to Cuba in 1984. The woman used to encourage anti-US voices by all possible means from Cuba, New Jersey police sources said.
The authorities have doubled the reward for Chesimard's capture and safe return to USD 2 million.
The police said they want Chesimard to return and serve out her sentence.
Chesimard, who is known to be the godmother of slain rapper Tupac Shakur, is said to be a supreme terror to the US although she doesn't involve with a new threat. Chsimard's supporters believe that she was targeted by the law enforcement officials while campaigning against the Black Panther Movement in the 1960s and 1970s.
