The widow of an NYPD cop who was killed in the line of duty by a drunk driver honored her hero husband by hosting blood drives ahead of Father’s Day.

Irene Tsakos, the widow of Detective Anastasios Tsakos, held two blood drives Thursday: one at NYPD Highway Patrol Unit 3 where her husband used to work, and another at St. Paraskevi Greek Orthodox Church, where her husband’s funeral was held.

Irene, who was joined by her 6-year-old son Steven, told The Post the blood drive was in memory of her husband.

She plans to hold a blood drive every year around Father’s Day, she said,

The 43-year-old father of two was posthumously promoted to detective after he was killed three years ago in a drunken hit-and-run on the Long Island Expressway.

Irene made headlines during the trial last fall when she burst into tears after hearing a witness describe her husband’s gruesome injuries.

Prosecutors said driver Jessica Beauvais, 34, was high on drugs and had a BAC of .15 when she slammed her 2013 Volkswagen into Anastasios while he was investigating an accident in the early hours of April 27, 2021.

The 14-year veteran lost a leg and his organs were crushed when he landed 171 feet from the impact — but Beauvais just drove off, prosecutors said.

Hours before the fatal 2 a.m. crash, Beauvais was seen on a live podcast posted to Facebook slamming shots while going off on an anti-cop rant.

Beauvais’ attorney argued Anastasios should have been wearing more safety gear.

A judge sentenced Beauvais to 27 years in prison, with an opportunity for parole after 22 years.
