Sunmara Alexander, the surviving sister of a teen killed in a Christchurch car crash two weeks ago, has died in hospital on her 16th birthday.
The sisters' father, Jason Alexander, announced his younger daughter's death on Facebook on Friday night.
"It is with great sadness I tell you this, my beautiful baby girl passed away at 8.27 tonight," he wrote.
Sunmara, 16, and sister Tayla, 17, were passengers in a car that went over a bank and burst into flames on Summit Rd, on the Port Hills.
