86yo run down in 'cowardly' hit-run in Adelaide

Police have described as cowardly a motorist who left an elderly woman critically injured on the road in Adelaide.

The 86-year-old woman was crossing her street at Alberton when a car hit her, fracturing her head and pelvis.

Residents of Melbourne Place found the woman lying on the road on Saturday night and think she had been crossing it to feed birds in a park, something she did daily.

Neighbour Elizabeth Rudkin thinks the driver involved was callous.

"When I went out there was a lady lying on the middle of the road in the cold and the wet and it was windy and she was groaning and I just felt so awful," she said.

"How could someone do this?"

Superintendent Linda Fellows is urging the driver to come forward.

"It's incredibly cowardly, it's disappointing and I think any person who understands that an 86-year-old woman is fighting for her life in hospital would have to look at their conscience and come forward," she said.
