Thousands attend vigil for hit-run victim Andrea Lehane

The husband of a young mother who died after being knocked down outside a Melbourne shopping centre has spoken of his wife's caring nature.

James Lehane joined thousands of people who paid their respects at a candlelight vigil for his wife Andrea, 33, at the Carrum Downs shopping centre car park on Sunday night.

Ms Lehane was fatally injured when she was allegedly hit by a mini-motorbike as she crossed the road to the car park on Wednesday.

Family members turned off the mother-of-two's life support on Friday and donated her organs after she suffered "unsurvivable" brain damage from the crash.

Mr Lehane told the crowd on Sunday he would be a strong father for his children.

Caleb Jakobsson, 18, faced court over the hit-run death on Saturday and was remanded in custody to appear on Tuesday. Two others have also been charged.
