Investigators say 20-year-old Dejuan Rene Smith was pushing her 14-month-old daughter in a stroller on Balsam Road near Lone Eagle Street about 10:30 p.m. Friday when a Ford pickup truck hit her from behind and fled the scene.
Smith, who was five to six months pregnant, died at the scene. The unborn baby died as well. Her daughter suffered minor injuries from being thrown from the stroller.
"We just want closure, especially for this little baby left without a mother," said Smith's mother, Reba Wilson, at a press conference Tuesday.
Authorities say they don't have any suspects. They say the pickup truck had front-end damage to the right side and was missing its right mirror.
Smith was walking home from Wal-Mart at the time.
"This fool took it upon himself to just drive off after hitting her," said Chillie Mo, Smith's brother. "They need to come forward, stop being a coward and hiding, and thinking he got away with something.
"You're not going to get away for too long, because as they say: what goes on in the dark, will come out in the light, and you will be caught and justice will be served."
Anyone with information is asked to call the San Bernardino County Sheriff's Department at (760) 241-2911.
