Rosa Ramirez, of New York City, pleaded guilty in February to charges of second-degree murder in the fight that killed her prep cook co-worker, Bonifacio “Boni” Rodriguez, at River City Grille in Irvington on April 10, 2018.

She was sentenced Thursday to a minimum of 17 years and up to life in state prison for her crimes.

Police investigators never said what Ramirez and the dead co-worker had been fighting about prior to the deadly attack.

She had only worked at high end River City Grille for a few days at the time of the fight. 

Bonifacio Rodriguez, meanwhile, had worked there for two decades.

Prosecutors say Rosa Ramirez was working as a dishwasher along with other kitchen staff around 11 a.m. that deadly April day that she attacked the 38-year-old Rodriguez with a kitchen knife, though didn’t elaborate on what happened before.

Boni Rodriguez tried to protect himself but was stabbed multiple times, prosecutors said; the Yonkers man was pronounced dead at a hospital. 

No employees in the kitchen intervened to save him from the knife weilding woman.
