A fourth person has died after police say a drunk man plowed a pickup truck into a park on the Lower East Side on July 4th, bringing the number of fatalities from the incident to four.

Emily Ruiz, 30, spent five days in critical condition at Bellevue Hospital before she died from her injuries on Tuesday, according to information provided by the NYPD.

Police said she lived in the Vladeck Houses, a NYCHA complex right across from Corlears Hook Park, where families were celebrating the holiday when 44-year-old Daniel Hyden allegedly lost control of his truck and careened into the crowds.

Lucille Pinkney, 59, and Hernan Pinkney, 38, were killed immediately at the scene. The third person, 43-year-old Ana Morel, died at Bellevue Hospital the next day.

Hyden, of Monmouth Junction, NJ, was charged with vehicular homicide, eight counts of assault, three counts of driving while intoxicated and one count of “aggravated unlicensed operator,” or driving with a suspended or revoked license.

He was arraigned Saturday in Manhattan Criminal Court, where he pleaded not guilty to all charges, and was ordered held without bail.

Hyden had previously worked as a substance abuse counselor at a center in East Harlem, according to police and an employee at the site.
