Suffolk D.A.: Medford man indicted for fleeing scene of fatal crash

Dolores Mancialandaverde Allegedly Attempted to Evade Responsibility by Fleeing on Foot After Crashing into a Tractor Trailer

On July 16 Suffolk County District Attorney Raymond A. Tierney announced the indictment of Dolores Mancialandaverde, 28, of Medford for leaving the scene of an incident without reporting, and other related charges for allegedly operating a motor vehicle while his privilege to drive in New York State was suspended, and then leaving the scene of a crash that resulted in the death of his passenger, Hedilberto Nava-Perez, 44, of Medford, and serious physical injuries to another passenger.

“After slamming into a tractor trailer, this defendant allegedly cared more about evading responsibility for his actions than rendering aid to his own friends and passengers,” said District Attorney Tierney. “My office will seek justice for the victims in this case, including Mr. Nava- Perez who tragically lost his life.”

According to the investigation, on June 8, 2024, at approximately 1:52 a.m., Mancialandaverde was allegedly driving his 2008 BMW 328i southbound on Horseblock Road in Medford, with two passengers inside.

As a tractor trailer was making a left-hand turn from Horseblock Road onto Express Drive North, Mancialandaverde allegedly drove through the intersection and crashed into the tractor trailer. Mancialandaverde allegedly exited his vehicle and fled on foot as a bystander attempted to render aid to the victims.

Nava-Perez, Mancialandaverde’s back-seat passenger, was pronounced dead at the scene. Mancialandaverde’s front-seat passenger suffered femur, spinal, and facial fractures, and was airlifted to Stony Brook University Hospital. The driver of the tractor trailer was uninjured.

At the time of the crash, Mancialandaverde’s privilege to drive in New York was suspended.

On July 16, 2024, Mancialandaverde was arraigned on the indictment before Supreme Court Justice Timothy P. Mazzei, for the following charges:

 Leaving the Scene of an Incident Without Reporting, a Class D felony;
 Leaving the Scene of an Incident Without Reporting, a Class E felony; and
 Aggravated Unlicensed Operation of a Motor Vehicle in the Second Degree, an Unclassified misdemeanor.

Justice Mazzei ordered Mancialandaverde held on $50,000 cash, $100,000 bond, or $500,00 partially secured bond during the pendency of the case. Mancialandaverde is due back in court on August 18, 2024, and he is being represented by Luigi Belcastro, Esq.

This case is being prosecuted by Assistant District Attorney Jeffrey Rosenheck of the Vehicular Crime Bureau, and the investigation was conducted by Detective Donal Hughes of the Suffolk County Police Department’s Major Case Unit.
