The driver who was killed Thursday in Costa Mesa by a eucalyptus tree has now been identified as 29-year-old Haeyoon Miller of Tustin.
Miller was in her vehicle about 2 p.m. stopped at a red light on Irvine Boulevard when the tree fell from the center median, crushing her car and killing Miller. She was alone in her vehicle.
A helicopter was called to the scene to help airlift Miller to a hospital but she was pronounced dead before it arrived.
The tree is estimated to have been between 40- and 50-feet tall. The cause of the tree collapse was not released.
