The FBI offices in New York and Philadelphia were hopeful Friday  they’re a step closer to capturing two, female radicals who’ve been fugitives since the 1980’s.

Donna Joan Borup and Elizabeth Anna Duke are believed to be traveling together, and the Port Authority Police of New York and New Jersey have a particular interest in Borup.

32 years ago this week, on September 26th, 1981,  police said Borup and accomplices tossed a caustic substance into the eyes of Port Authority Police Officer, Evan Goodstein, during an anti-apartheid demonstration at John F. Kennedy International Airport in Queens.

“He was partially blinded in one eye,” the current Chief of Police, Louis Koumoutsos, told PIX 11.

Borup—who was born in South Amboy, New Jersey–was arrested but later released on bail , pending a trial in May 1982.  When Borup failed to show up for the trial, a federal arrest warrant was issued.

Borup, who was then 30 years old, belonged to the May 19th Communist Organization, which advocated armed revolution and the violent overthrow of the United States government.

Elizabeth Anna Duke, from Texas, also belonged to the group.

Duke had ties to a man connected to the 1981 Brinks armored car robbery in Nanuet, New York—which left a security guard and two police officers dead.  Duke and the man were arrested in Bucks County, Pennsylvania in 1985.  Duke was released on bail  and later fled that jurisdiction.  She has been a fugitive since October 1985.

The Port Authority police chief told PIX 11 there are new leads in the search for the two women.  The Port Authority is working with the FBI to capture them.  Borup and Duke have ties to the Pennsylvania area, and Duke has been known to travel near the Canadian border.

The FBI features a 2011 “age progression” photo on Borup’s poster.  She is now 61 years old.  Duke, who would be close to 70, does not have a similar picture on her “Wanted” poster.

Anyone who gives the FBI or Port Authority police a tip that leads to the arrest of either woman will receive a $50,000 reward.
