TUCSON, AZ (Tucson News Now) - On Friday, 20-year-old Dominic Romero was killed on North Anway Road between Orange Grove and Manville.
Friends and family of his have created a memorial at the site in his honor as they continue to search for answers.
"There's not one person out there that ever met my son that could ever say anything bad about him," said Michelle Arbizo, Dominic Romero's mother. "He would always tell me mom - I'm living like there's no tomorrow."
Arbizo said he did. She spent her Sunday with family, and adding to the growing memorial inside her home.
Crosses, photos, and rosaries depicted the love Dominic Romero had for life, for rodeo and for his support system.
"He put everyone first. He always made sure every one was taken care of," explained Robert Romero - Dominic's father.
That trait his family said he's carried with him, even after he's gone.
"Without him, I don't know where I would be.I know right now he's giving me the strength to get through this," said Arbizo.
His memory also lives on at the scene of the crash that killed him.
In a release, the Pima County Sheriff's Department said the 20-year-old was walking home down North Anway Road early Friday morning - on his birthday.
He was hit and killed. That driver who hit him left and never came back.
"I don't know how they can sleep at night, knowing what happened," said Arbizo.
As the days go on - Dominic's family wants to know who drove off.
"Just put yourself in our shoes. It's the right thing to do," explained Danny Arbizo, Dominic's uncle.
They're like anyone who knows something to come forward and hopefully give them some closure as they more the loss of their loved one.
"He was my everything," said Arbizo.
The Pima County Sheriff's Department says they are looking for a blue or green pickup truck, possibly with a diesel engine. It may have had marker lamps on the cab.
