CLARKSTOWN, N.Y. -- Several hundred people lined a New York state Thruway entrance Tuesday to honor two Nyack police officers and a Brinks armored car guard killed during a 1981 robbery by a group of self-professed revolutionaries, according to lohud.com.
On Oct. 20, 1981, six men armed with high-powered weapons jumped from the rear of a U-Haul truck at a roadblock and fatally shot Sgt. Edward O'Grady and Officer Waverly "Chipper" Brown. Nyack Detective Arthur Keenan and Officer Brian Lennon were injured.
Just 30 minutes before the roadblock slayings, the gunmen killed Brinks guard Peter Paige and wounded guard Joseph Trombino at the Nanuet Mall during the robbery of $1.6 million, reported lohud.com.
The robbery was committed by members of the Black Liberation Army members and former members of the Weather Underground and other radical groups of the 1960s and 1970s, lohud.com said.
