police arrest aunt, 25-year-old lorysah gage. over the weekend, family members passing out flyers about the hit-and-run. gage had just taken the kids to watch "teenage mutant ninja turtles" when the girl was killed. the question is whether the driver knew he or she hit the girl, the driver had the green light when it happened. >> obviously a tragic incident, emotional, as you can imagine with the arrest of the aunt and the passing of her niece and someone's 2-year-old daughter. >> reporter: again, police looking for the driver of the car that hit mi'yana, shown in this video. it's a mid 1990s white four-door sedan, could be a camry, lexus, honda with a dark mismatched bumper. back here live, one of the posters in that memorial for mi'yana. the aunt, again, gage, facing felony child endangerment charges, booked into san francisco county jail. coming up in our next report, half an hour, how you can help the family other than helping police with information about the driver, how you can help them in moving forward. stephanie chuang,
