An NYPD officer was indicted on Monday for second-degree murder in connection with the “road rage shooting” death of Delrawn Small on July 4.

Wayne Isaacs, an NYPD officer of three years assigned to the 79th Precinct in Bedford-Stuyvesant, will be arrested on Tuesday, New York Daily News reported, for allegedly shooting 37-year-old Small in front of witnesses on Atlantic Avenue in East New York after a confrontation.

Small believed he was cut off by the off-duty Isaacs, officials said, and he proceeded to chase the off-duty officer’s car for seven blocks. When the chase turned into a confrontation, Small approached Isaacs’ car. Isaacs previously claimed Small punched him in the face, but video shows Isaacs opening fire just seconds after Small moved toward Isaacs car.

Small, who has a criminal record, had three glasses of alcohol at a barbeque before driving, his girlfriend, one of the three witnesses said, New York Post reported. Small was unarmed, according to reports.

"I am grateful to the attorney general in getting this indictment," Small's widow, Winona Hauser Small, said in a statement, according to the Daily News. "I will be in court for every appearance of the police officer, fighting for justice for the wrongful killing of my husband."

Isaacs is the first officer charged by the special prosecutor State Attorney General Eric Schneiderman since Gov. Andrew Cuomo signed new law appointing Schneiderman. The law was signed in August of last year, almost a year to the day after Eric Garner’s death during his arrest on Staten Island, the New York Post reported.

The police union representing Isaacs declined to comment, NBC4 New York reported.
