Ms Kaczan, who was held in a Nazi camp during the Second World War, told police she was attacked from behind, at 8.45am, close to the junction of St Chads Road and Empress Road in Normanton, Derby.
The prosecution alleges that after the incident, the defendant changed his appearance and the insurance details of the car he was driving to distance himself from the attack.
Opening the case against Waszkiewicz on Monday, Kate Brunner QC said: “She was attacked, she was thrown to the ground and her handbag was snatched from her.
“The prosecution say it was this man in the dock who robbed her and whose actions led to her death.
“She was small, on her own, vulnerable – an easy target for a man desperate for money.”
The court was told Waszkiewicz was questioned by police at his father’s address in Shepherd’s Bush, west London, where he admitted he had been driving the car on the day of the attack.
Ms Brunner said the defendant was caught on CCTV disposing of the handbag in a well-known fly-tipping area.
She continued: “He attacked Ms Kaczan, yanking her handbag from her and leaving her injured in the road and driving off.
