In four separate crashes since Thursday, at least two people have been struck and killed while walking, and two others were critically injured.

Last Thursday afternoon Giovani Romano hit 56-year-old Alfiya Djuraeva with a Buick while turning left at 20th Avenue and Bath Avenue in Bath Beach, according to the Daily News and WNBC. Djuraeva suffered trauma to her head and torso and died at Lutheran Hospital.

Romano, 74, was issued a desk appearance ticket for failing to yield, but was not charged for the act of killing Alfiya Djuraeva. The crash occurred in the 62nd Precinct and in the City Council district represented by Vincent Gentile.

Early Saturday morning, a BMW driver going the wrong way on 181st Street near Amsterdam Avenue in Washington Heights hit two people and a pickup truck, then fled the scene, the Daily News reported. A male pedestrian, 46, was killed. The second victim, a 46-year-old woman, was hospitalized. The deceased victim’s name was being withheld pending family notification, NYPD told Streetsblog.

[Update: The deceased victim of the Washington Heights crash was identified as Jorge Encarnacion.]

Police charged Jonathan Jonatan Segura, 34, with manslaughter, leaving the scene, and drunk driving, after Segura turned himself in, the News said.

Hours before the fatal Manhattan crash, another hit-and-run driver in a BMW critically injured a woman in Williamsburg. The motorist struck the victim, reported to be in her 30s, at around 1 a.m. as she attempted to hail a cab near the intersection of Rodney Street and Metropolitan Avenue, according to Gothamist. The driver was not caught.

At approximately 2:36 a.m. Sunday a yellow cab driver hit a 25-year-old man as the victim crossed W. 15th Street near 10th Avenue in Manhattan, the Daily News reported. A photo published by the News shows a pool of blood on the street a couple of car lengths away from a crosswalk.

The unidentified victim was in critical condition at Bellevue. The driver was not charged.
