Cobian was crushed when the 2001 Toyota pickup truck Olvera was driving rear-ended the 1994 Oldsmobile sedan she and her cousin were pushing, police said.
Cobian, of Glendale Heights, was transported to St. Alexius Medical Center, where she later died. Her father said his daughter was his sweetheart. She had four children, ages ages 9, 7, 3 and 6 months.
Her friend, Rhaven Becker, said Cobian was pregnant.
"She was scared at first, but she all kept saying is that it was meant to be, you know, she was 12 weeks," Becker said.
"It's just really sad that he claimed he didn't see her. She's human, you could have seen her," said Jasmine Stanley, the victim's friend.
Olvera is due in Bond Court in Rolling Meadows on Wednesday.
