The Phoenix Police Department said on Tuesday that a 7-year-old boy who was a victim of a deadly crash has died.
He was identified as Taviel Tyler.
He had been in critical condition since a driver hit a group of people on the sidewalk on Sunday.
Investigators said a 23-year-old man was heading south on 43rd Avenue near Maryland Avenue when he went off the road and hit the group.

Five people were taken to the hospital, including 17-year-old Hailey Newtown who later died. Three other people received treatment for injuries that weren't considered life-threatening.
The driver kept going and hit a northbound minivan that had eight people inside, police said. A 2-year-old suffered significant but not serious injuries.
The 23-year-old also hit a Toyota Tundra pickup truck. A Subaru was hit by debris. They were not hot.
The man is in the hospital with significant but not serious injuries.
Investigators are looking into whether impairment was a factor.
One witness said she believes two drivers started the chain-reaction crashes and that it had to do with road rage.
