Ryan McHugh, of the 4700 block of St. Dennis Drive in Philadelphia, is charged with two counts of homicide by vehicle, aggravated assault while driving under the influence, involuntary manslaughter and causing an accident involving death.
The family is building a memorial for 28-year-old Rosa Lydia Rojas near Aramingo Avenue and Tioga Street, where she was fatally struck around 9 p.m. Saturday.
Police say Rosa and her two children, 11-year-old daughter Leani and 9-year-old son Jadiyn, were standing along the road after getting food when McHugh's SUV jumped the curb and plowed into them.
Investigators said she managed to push her daughter out of the way. Rosa shielded her 9-year-old boy, but they were both hit.
The SUV driver took down a pole before hitting the mother and son.
Rosa was taken to Hahnemann University Hospital, where she died from her injuries. Her family says they know she died a hero saving her kids' lives.
Rojas' father shared his memory of his last moments with his daughter.
"The last time I spoke to her was two days ago. I should have told her how much I love her, but I didn't," Eugenio Rojas told ABC7's sister station WPVI-TV on Sunday.
"I've got to bury a kid knowing that it's not supposed to be like that. It's supposed to be my kids burying me and that hurts," Rojas said. "I wish I could bring my daughter back. I know I can't."
Jadiyn was taken to St. Christopher's Hospital. He is in critical but stable condition.
"He had a broken leg, broken arm. He got blood through his brain," Eugenio Rojas said.
McHugh was held by witnesses at the scene before being arrested by officers. He is being held on more than a half million dollars bail.
"I hope he rots in jail," said Eugenio Rojas.
Eugenio says he wants his grandson Jaydin to know everyone loves him and is pulling for him as he recovers in the hospital.
"My grandkids know how much grandpop loves them. I've got 12 grandkids and they know how much grandpop loves them. My grandkids mean the world to me," Eugenio Rojas said.
WPVI-TV learned that Rosa was about to get married.
"I just wanna tell you I love you baby, and I'm here for you, and I'm here for the kids," her fiancé Martez Smart said.
The family pleads for anyone thinking about driving under the influence to make a different choice. They don't want more families to have to go through the pain of losing a loved one.
