Investigators found the truck believed to have been involved about three miles from the scene.
Angel Villafuerte was a fifth-grade student at Nathan Hale Elementary School. His older brother was with him, about to cross the street, when Angel was struck.
As candles were lit at the scene Wednesday night, Angel Villafuerte is remembered by family.
"He was more than a brother, he was like a friend. We did everything together. . . He understood me, I understood him. We were complete soulmates, really," said Michael Calzada, brother.
"He was really a good kid, every time I seen him, he just made me smile," said Paula Cerda, Angel's aunt.
Friends point to pictures that show Angel's true personality.
"Cheerful, he laughed a lot," said Onyx Medina, Angel's friend.
Whiting Police say the boy was with his older brother, running through a gangway right toward Indianapolis Boulevard, just south of 119th.
"I think the wind of the truck, I don't know, pulled him. And then I don't know, it went so fast, and that's it, it just happened," said Calzada.
Police say the hit and run crash happened about 3:15 p.m. Witnesses watched the following seconds closely.
"My officers on the scene were given a description of the vehicle, and then, my officers three miles away were able to stop that vehicle," said Chief Steve Miller, Whiting Police Chief.
Police stopped the truck in Hammond at Sheffield and Calumet. The driver, who was with Indiana State Police Wednesday night, was hauling a load onboard a Decker trailer.
Back in Whiting, Villafuerte is on the minds of those who loved him.
"He was always running around, hanging out, having fun, playing games and just messing around with all the kids. He was always full of life, so that will be missed dearly," said Minister Paul Vale, New Life Christian Church.
"If you have a little brother or sister, please care about them, because you want to be in their lives for a very long time and you want to spend more time with them," said Calzada.
The minister at New Life Christian Church says they hope to help children on Friday night at the church.
