Rewards are being offered for information leading to the arrest of two long-wanted fugitives.
Authorities have amassed a combined $50,000 for information leading to the arrest and conviction of Donna Joan Borup.
According to officials, Borup is accused of hurling a substance at Port Authority Police Officer Evan Goodstein during an anti-apartheid protest at JFK airport in 1981.
Officials say the incident left Goodstein partially blind.
Borup failed to appear for her trial, and a warrant was issued for her arrest in May of 1982.
The Federal Bureau of Investigation is also offering up to $50,000 for information leading to the arrest and conviction of Elizabeth Anna Duke.
Authorities say Duke is possibly traveling with Borup.
Duke was arrested in 1985 for a series of alleged crimes, but like Borup, officials say she disappeared before her trial.
The FBI says Borup and Duke are both considered armed and dangerous.
