The 20-year-old woman was struck and killed early last Sept. 18 as she was crossing a street in Hamilton.
Due to the force of the impact, Hamilton police say her personal items were thrown several metres down the street.
Detectives say her purse contained a wallet with her identification and credit card and a credit card belonging to her boyfriend.
Police allege that while the woman's body was still on the street, a man took her purse and then fraudulently used the credit cards.
Jason Dave Trotter, 29, of Hamilton is charged with four counts of fraudulent use of a credit card, two theft charges and two possession charges.
