Miosotis Familia and her partner were sitting in their patrol car as usual not suspecting anything.

Suddenly, a suspected assassin opened fire on the New York City police officers.

New York City police, Sgt. Brendan Ryan, says 48-year-old officer Miosotis Familia died at a hospital early Wednesday in what police are calling a "clear assassination".

Police say other officers shot and killed the suspect after he drew a revolver on them.

They say the attack happened in the Bronx just after 12:30a.m. while the officer was sitting in her vehicle with her partner.

Her partner radioed for help while other officers spotted the suspect and began chasing him.

The suspect has been identified as 34-year-old Alexander Bonds.

Ryan says police are unaware of any connection between Bonds and Familia.
