A one-time safe cracker who was a guest at Justin and Nicole Scherer’s wedding reception last year stole a box full of gifted cards, pilfered the cash and flushed the cards down a toilet.

The $475 stuffed in Jennifer Ann Martz’s bra helped lead to her conviction Thursday.

A Butler County jury, after hearing the story, was convinced beyond a reasonable doubt that Martz, 42, of Chicora is the thief. At the conclusion of a one-day trial, a 4-man, 8-woman jury convicted Martz of theft and receiving stolen property.

She will be sentenced later by Butler County Judge William Shaffer, who presided over the trial. He additionally convicted Martz of a summary count of criminal mischief.

Martz, who testified, denied any wrongdoing.

The incident began when a different guest at the June 8, 2013, event couldn’t flush the toilet. The problem was caused by 11 soggy, tattered cards.

Witnesses, including the bride, had seen Martz lingering near the gift box — a cardboard box covered in white paper and pink and green pipe cleaners fashioned into bows.

“She told me she really liked pipe cleaners and asked if she could have some,” recounted bride Nicole Paugh Scherer.

Another witness said the toilets in the ladies room at the Donegal Grange worked before Martz went in. And, the groom’s brother testified that after the discovery, he saw Martz trying to sneak a wad of cash into the facility’s Dumpster.

That’s when a crowd of guests forcibly retrieved the money from Martz and detained her until state police arrived. One guest alleged that Martz kicked, flailed, tried to leave and created a scene.

But Martz testified she was assaulted by a group of men to such a degree that she was treated later at Butler Memorial Hospital for a mild concussion.

She testified the crowd falsely accused her of taking the money, roughed her up — ripping her dress and slamming her to the ground — and began “going up and down my dress” until they discovered and removed $475 that she’d tucked into her bra.

Martz, as well as her live-in boyfriend and wedding date 45-year-old George McCray, claimed the money was set aside to pay property taxes.

It had been in Martz’s purse earlier, both testified, but she chose to leave the handbag in the car during the wedding reception and instead keep the cash in her blouse “for security,” McCray testified.

“Who would do that?” questioned Laura Pitchford, a certified legal intern who prosecuted the case for the Butler County District Attorney.

Pritchard described the defendant as “unemployed.” And Martz, while on the witness stand, described herself as having been on disability since age 27 for multiple sclerosis and depression.

Pitchford also openly doubted Martz’s story that she and McCray had only recently retrieved the cash from a bank machine because the mix of bills recovered included $5 and $50 bills. Banking machines, Pritchard said, don’t often give out those denominations but wedding guests do.

Defense attorney Joseph Smith, during his closing argument, stressed the lack of direct evidence in the case. No one saw who took the cards or who flushed them in the bathroom that was used by a good share of the party’s 100 guests.

Martz after the verdict declined to comment.

The judge did acquit Martz on an additional summary charge of disorderly conduct.

Martz, whose criminal record includes felony convictions in 1989 in North Carolina for safecracking, larceny and breaking and entering, is free on $2,000 bail until her sentencing.

Before the trial, Shaffer ruled prosecutors could not tell the jury about Martz’s previous convictions because they are 25 years old and she was 16 at the time.
