*695 Appeal by the defendant from a judgment of the County Court, Suffolk County (John J. Toomey, J.), rendered March 23, 2015, convicting him of manslaughter in the second degree, upon a jury verdict, and imposing sentence.
ORDERED that the judgment is reversed, on the law and as a matter of discretion in the interest of justice, and the indictment is dismissed without prejudice to the People to re-present any appropriate charges to another grand jury (seePeople v. Beslanovics, 57 N.Y.2d 726, 727, 454 N.Y.S.2d 976, 440 N.E.2d 1322); and it is further,
ORDERED that pursuant to CPL 470.45, the matter is remitted to the County Court, Suffolk County, and that court shall cause the defendant to be brought before it forthwith, at which time that court shall issue a securing order in accordance with the provisions of CPL 210.45(9).
Nonetheless, we reverse the judgment because the County Court should have granted the defendant's request to submit to the jury the charge of criminally negligent homicide as a lesser included offense of manslaughter in the first degree. The prosecutor's improper use of the defendant's post-arrest silence to impeach the defendant's testimony at trial and the prosecutor's improper comments during summation are additional bases for reversal.
