STAMFORD — A Stamford man has been charged with driving on a suspended license, weeks after posting bond and getting out of jail while he waits to face charges of manslaughter and driving under the influence for his alleged role in a fatal crash in the South End last August.

Officner Lindsay Yanicky, who helped investigate the double fatal crash last summer, spotted Jerry Diaz behind the wheel of a black Infinity near the Stamford railroad station last Thursday, Sgt. Jose Alvarez said.

Diaz faces serious charges stemming from last summer’s incident. Police say he crashed his mother’s Nissan Altima into utility poles on Canal Street early in the morning of Aug. 26. He had five passengers in the car at the time, police said.

Stamford residents Nishawn Tolliver, 18, and Ky-Mani Antoine-Pollack, 19, died in the crash. Two female passengers in the car suffered serious injuries. Police said Diaz was driving under the influence of alcohol and speeding down Canal Street prior to losing control of the car.

Officers in the city had recently been issued a memo reporting that Diaz had been seen seen driving around Stamford, police said. One of the conditions of his release imposed by Judge Richard Comerford was that Diaz, who still has a scar across his left temple from the deadly crash, cannot drive until his license is legally reinstated.

Prior to his release, Diaz had been held on a $250,000 court-appearance bond.

Diaz was driving with a suspended license at the time of the crash, according to police.

His attorney Howard Ehring said he was aware of the most recent arrest.

“We are looking into the allegations of the case and I understand the position the state has taken as far as its prosecution of Mr. Diaz is concerned,” Ehring said on Thursday morning.

At the time of last August’s crash, police say Diaz, 18 at the time, had a blood-alcohol concentration of .137 percent, well above the .08 legal limit, according to police. For those under the age of 21, the legal limit is .02.

Police said Diaz was driving as fast as 96 miles per hour prior to the crash.

Two of Diaz’s three female passengers, Amaiya Callahan and Alontia Moore, suffered serious injuries, including broken bones and brain hemorrhages, according to court documents. Erica Stephens suffered a lung contusion. Both Antoine-Pollack and Tolliver died from blunt-force trauma.

Along with other charges, including reckless driving and driving under the influence, Dias is facing two counts each of second-degree manslaughter and second-degree manslaughter with a motor vehicle, Class C felonies, punishable by up to 10 years in prison. Other charges he faces are second-degree assault and second-degree assault with a motor vehicle, which are both Class D felonies and punishable by up to five years in jail.
