One of eight people killed in a Florida crash died without knowing her fiancée was pregnant

One of the farm workers who died in an accident in Florida on Tuesday was earning money for his upcoming wedding and had no opportunity to learn that his fiancée was pregnant, according to his mother.

Alfredo Tovar Sanchez, 20, was among eight farm workers killed when the bus he was riding in collided with a pickup truck early Tuesday morning, injuring nearly 40 people, authorities said at the time, according to the Associated Press. All of the victims were harvest workers from Mexico.

All eight victims killed were identified by authorities on Friday, Click Orlando reported.

Ernesto Ruiz, a researcher with the Farmworker Association of Florida, confirmed the names of the victims, including Sanchez, to PEOPLE: Isaias Miranda Pascal, 21; Santiago Benito De Jesus, 24; Cristian Salazar Villeda, 24; Jose Heriberto Fraga Acosta, 27; Everado Ventura Hernandez, 30; Oscar Temoxtle, 31; and Manuel Perez Rios, 46.

Bryan Maclean Howard, the alleged driver of the pickup, was arrested in connection with the crash, Florida Highway Safety and Motor Vehicles said Tuesday. He is charged with eight counts of involuntary manslaughter.

It’s not clear whether he entered a plea or hired an attorney.

The workers — both those injured and those who died — were part of a cohort of immigrants who were in the U.S. specifically for agricultural work and had visas that did not allow them to bring their family members, Ruiz tells PEOPLE.

As authorities at the Mexican consulate in Orlando work to help the victims’ families in Mexico, Sanchez’s mother told Telemundo News her son was preparing for his wedding and died, unaware that his fiancée was two months pregnant is, as NBC News reported.

“I feel like I can’t go on without my son,” María Sánchez said in the interview from her home in Mexico. “I was in so much pain. I don’t know if I can live with this pain.”

She said Alfredo was working in Florida to earn money for a new future, which included building a house and getting married.

According to the outlet, Maria expressed concerns that Alfredo’s fiancée, who is 17 years old, will face several challenges after the child’s birth.

“If they arrest the person responsible, all I demand is justice,” she told Telemundo News.

The workers caught in the crash were living in Florida at the time of the accident but were scheduled to leave the state later in the week to go to another farm, Ruiz tells PEOPLE.

A GoFundMe launched by the Farmworker Association of Florida raised nearly $80,000 for the workers and their families.

“Farm workers are often forgotten, but it is important not to forget them, especially during such difficult times,” the fundraiser said.
