Deadly Revere Crash: 2-Month-Old Dies Days After 5-Year-Old Sister

REVERE (CBS) -- A two-month-old baby has died days after a crash in Revere that already killed her sister.

On Sunday evening, two adult women, a five-year-old girl, a two-year-old child, and a two-month-old girl were "on a sidewalk inside the median strip that divides both sides of Route 145" when an SUV driven by 42-year-old Autumn Harris hit them, Mass. State Police said.

Suffolk District Attorney John Pappas said five-year-old Adrianna Mejia-Rivera was pronounced dead at the scene. Natasha Nicole Mejia-Rivera, two months old, died Wednesday night.

At a vigil Thursday night, the girls' father choked up as he thanked a crowd of hundreds who gathered to mourn.

"It's a pain that he cannot explain," Edgar Mejia said through a translator. "And he also wants to tell the authorities, please do justice for what happened with his daughters."

Harris appeared in Chelsea District Court Monday for her arraignment. She was visibly upset as prosecutors described the scene and she was charged motor vehicle homicide and negligent operation of a motor vehicle.

Pappas said Harris told police she slept only two hours before working all day. Prosecutors say Harris also admitted she vaped CBD oil in her SUV and might have nodded off at the wheel.

"I have no words for that person," said Renee Burns, who came to Thursday night's vigil. "I don't know how that person, can you know sleep at night."

Prosecutors had tried to stop Harris from getting back on the road once before after she was acquitted for driving under the influence in 2014, but a judge reinstated her license.

The mother of the two children who died was also involved in the crash. She suffered non-life threatening injuries.

"Our priority right now is supporting a family who lost the center of their world in the blink of an eye," said Pappas.

Harris is due back in court January 10.

A GoFundMe account has been set up to help the Mejia-Rivera family pay for burial services.
