A family party gave a Pekin woman and her boyfriend the opportunity to steal a purse from the car of the woman’s grandmother.

They took it, then used the grandmother’s credit card to buy hundreds of dollars worth of items before their arrest Monday, charges filed Wednesday allege.

Haley Heilman, 23, and Lee Frantz, 28, both of 603 N. 11th St., were charged with one count each of burglary and unlawful possession of a credit card. Bonds were set at $7,000 and $8,000, respectively, pending their arraignments on June 23.

Heilman’s grandmother said she discovered her purse missing from her car after the party Sunday that Heilman had also attended but left earlier. Frantz was not allowed to attend the affair, the victim said.

Other family members said they saw Heilman drive by the residence about an hour after she left. Heilman later told police she and Frantz had decided to return to the party to check the grandmother’s unlocked car for money, according to a prosecutor’s court affidavit.

Before the grandmother could cancel all of the credit cards her purse contained on Monday, the couple had used it eight times at four stores, the affidavit stated. While it did not detail the amount of purchases made with the card, the couple were initially arrested for theft over $500.
