A man who stole the purse of a dying elderly woman who was lying in the road having been hit by a lorry is being sought by Greater Manchester Police.
The 82-year-old was killed when she was struck on Leigh Road, Leigh, at about 11:45 GMT on Wednesday.
Police said that after the crash, officers were told a man "was seen to steal her purse before leaving".
The man is described as white, about 6ft (1.8m) tall, between 30 and 40 and of medium build with a brown beard.
Det Sgt Neil Lawless said it was "one of the most disgusting crimes I have ever investigated".
"I find it hard to believe that someone could stoop so low to commit such a horrific offence," he said.
