Today marks eight years since two NYPD detectives
were killed in an ambush in Brooklyn while on duty.
Detectives Rafael Ramos and Wenjian Liu were
sitting in their patrol car in Brooklyn on Dec. 20, 2014.
Authorities say that is when a gunman walked up to the passenger side
and shot both officers -- killing them.
A memorial plaque is now dedicated to them at the
84th Precinct, where they both worked.
