A Hempstead father who Nassau police said crashed his car into a tree in Westbury in 2013 while suffering an apparent medical emergency, killing his female companion and their 4-year-old son, will be indicted Monday on charges related to their deaths, authorities said.

Renen Vides, 29, of 11 Meriam St., was arrested Friday after Garden City police officers observed him driving a 2011 Nissan Sentra with no front plates on Clinton Street, Nassau police said in a news release Saturday.

Authorities then discovered a pending arrest warrant related to a sealed indictment connected to the 2013 crash, said Brendan Brosh, a spokesman for the Nassau district attorney's office.

The indictment, on charges including two counts of second-degree manslaughter, will be unsealed at Vides' arraignment Monday in County Court in Mineola.

It was unclear Saturday why Vides was charged in the deaths. Brosh declined to comment further.

A news release from the Nassau police department the day of the Sept. 29 crash said the driver "appeared to have suffered a medical emergency, veered abruptly to the right, mounted the curb and struck a tree."

Vides' companion, Martha Hernandez-Majano, 27, of Uniondale, who was in the front passenger seat, and their son, Renen Vides Jr., who was in a booster seat in the rear of the car, were taken to a hospital, where they later died of their injuries.

Vides suffered multiple injuries and also was taken to a hospital after the crash, which occurred on Old Country Road near The Source Mall.

Vides was arraigned Saturday in First District Court in Hempstead on several traffic law violations related to Friday's traffic arrest, including unlicensed operation of a motor vehicle.

Vides was in custody at Nassau County jail late Saturday afternoon, where records show Judge Joseph Girardi had ordered him held on $2,500 bail.
