Dias' parents told ABC7 News their son was a kind man, who had returned to his job as a crossing guard at Stanley a couple days ago.
"It is hard. It is unbelievable," said Dias' father Fabio Dias. "Just this morning we spoke to him in the afternoon at 2 o'clock just before he went to the crossing."

Jeanine Arnold told us her kids were nearby on their bikes.
"My kids were in the crosswalk yesterday," said Arnold, choking back tears. "I met them on the trail. They rode their bikes, dropped their bikes, just came to me, hugged me. They were crying and they had a hard time sleeping last night."
This accident comes as Lafayette and other districts are facing a severe shortage in the number of people willing to step up and be school crossing guards.
The company that hires for Lafayette schools posted recently about a desperate need for crossing guards, who are paid 56 dollars per day.

"We are having difficulty finding folks who are willing to step forward. It's not high paid work. People just want to help their community," explained Patricia Pohl, Vice-President of All City Management Services. "I don't know how we describe the profound sadness at the loss of this young man's life."
Pohl told us Dias' death was the first fatality in her company's history.
"He was a hero," said Arnold. "I just feel gratitude for him and the life he lived that led him to be here in that place to protect those kids."
ABC7 News has confirmed the driver of the car was a grandmother picking up her grandson. The woman's son told us the family is "devastated" by what happened.
