Surveillance video helped Ottawa police identify a suspected purse-snatcher in June.

Now, a month later, investigators are continuing to gather evidence that shows how much damage a person can do when armed with someone else’s identity and financial cards.

A 24-year-old Ottawa woman suspected of stealing the purse is facing about 20 criminal charges — including identity theft, fuel theft and criminal use of a financial card — in connection with the case.

A 75-year-old Princeton woman reported to Ottawa police June 11 that an unknown suspect stole her purse from a shopping cart at Walmart Supercenter, 2101 S. Princeton St., Ottawa.

Police investigators identified a suspect from a Walmart video surveillance recording and arrested Marsha Riley June 13 on suspicion of stealing the purse, Capt. Adam Weingartner, with the Ottawa Police Department, said in an email.

Financial cards taken from the victim were used at various businesses in Ottawa, Weingartner said. A follow-up investigation has been ongoing since the initial report, and Riley was arrested Thursday by police at the Franklin County jail, 305 S. Main St., Ottawa, on 19 additional charges, according to the arrest report.

She remained in the county jail Friday afternoon awaiting a court appearance.

Those additional counts included 12 charges of criminal use of a financial card, three charges of identity theft, three charges of fuel theft and one charge of theft of property or services.

“The investigation is still ongoing, and additional arrests are likely,” Weingartner said.
