Jury selection began Monday in the second trial of Ann Marie Drago.
Suffolk County prosecutors say Drago, of Patchogue, fatally struck anti-gang activist Evelyn Rodriguez during an argument in Brentwood five years ago.
Drago was convicted of criminally negligent homicide at her first trial, but a state appeals court tossed out the conviction in 2022.
The ruling said the prosecutor in the case mischaracterized evidence and confused the jury.
