A Powder Springs man has died three weeks after he was seriously injured in a crash in Austell, authorities said.

Kahlil Harper, 30, died Sunday at Wellstar Kennestone Hospital, where he was taken after the Dec. 10 early-morning crash on C.H. James Parkway, according to Cobb County police spokeswoman Shenise Barner.

Investigators said Harper was turning left onto Humphries Hill Road about 4:10 a.m. when his 2006 Infiniti G35 was struck by a 2017 Toyota RAV-4 driven by a 64-year-old Dallas man. Harper was taken to Kennestone with life-threatening injuries.

No charges have been filed against the driver of the Toyota. He was taken to Wellstar Cobb Hospital with injuries that were not life-threatening.

The investigation is ongoing. Anyone with information is asked to contact Cobb police at 770-499-3987.
