"To know that they are responsible for at least come forward and be willing to talk about that, it would be helpful," said Christopher Barker, boy's uncle.
Last Thursday, Ashton, his 9-year-old brother, Savion Smith, and their 69-year-old grandfather, Jess Barker, were returning from an outing along the lakefront when the accident happened. A car slammed into them as they walked in the crosswalk with the light near 67th and South Shore Drive.
Ashton was killed and his brother and grandfather were injured.
"They are some great children, great children. Just seeing their report card, they were A students," said Gloria Price, family friend.
Relatives and friends say Ashton's brother is still reeling from the loss of his best friend and his grandfather -- who is still hospitalized -- was hit especially hard by the deadly accident.
"He did take them from place to place, to the beaches, the museum or wherever he had to go," said Floyd Murphy, family friend.
Police continue to search for the car that struck the three -- a 2005 white or cream colored Ford Taurus with front end and windshield damage.
No suspects are in custody.
