STATEN ISLAND, N.Y. - She was on the verge of being sentenced for stealing from her last job, and she needed some time off from her current one.



So when Rebecca Thybulle's father was selected as a call-in for jury duty starting Oct. 13, authorities say the 32-year-old human resources manager from New Dorp Beach saw the summons as an opportunity to take a vacation.



Prosecutors allege Ms. Thybulle, of Winham Avenue, took the jury summons, photocopied it, then altered the photocopy so her name appeared instead.



She then presented the phony summons to her boss at the Children's Home Intervention Program (CHIP) on Amboy Road in Great Kills, according to court papers. The program is funded by the state Department of Health, and provides instruction and therapeutic services to developmentally disabled children.



On Oct. 14, Ms. Thybulle took the day off, called in to say "I was picked for jury," and didn't return until Tuesday, court papers allege.



"I was on a vehicular homicide case," she told a clinical director there, court papers allege.



Except she had left on her work desk "a sheet of paper with all of the necessary changes" to switch the summons from her father's name to her own, and her boss, CHIP director Lois Bond, discovered it and called authorities. A detective with District Attorney Daniel Donovan's NYPD detective squad arrested Ms. Thybulle at work Tuesday.



She told investigators, according to a law enforcement source, that she "in no way" benefited financially, since the job doesn't pay employees for days taken off for jury duty.



Rather, she said, she just needed the time off, and "my boss would not allow it without a good excuse, and even then she constantly badgers you about it," the source said.



Her father never showed for jury duty, though it's not clear if he ignored the summons or never saw it to begin with, the source said.



It turns out Ms. Thybulle had pleaded guilty to attempted grand larceny in Manhattan last month, and was awaiting a Nov. 16 sentencing date that could put her in prison for up to three years.



In that case, Ms. Thybulle, was working at The Coffee Shop, a bar and restaurant in Union Square, where she was responsible for payroll, authorities said. She continued writing paychecks to a former employee there, except she diverted the checks to her own bank account, pocketing $6,400, according to court papers.



Police arrested her in that case on Jan. 18.



Authorities say she also failed to tell her employers at the CHIP that she had been convicted of a felony in 2002 in a Medicaid fraud case.



A message left for officials at the CHIP was not returned yesterday, nor was a message left on Ms. Thybulle's voicemail.



Ms. Thybulle faces two counts each of second-degree forgery and second-degree criminal possession of a forged instrument, said Donovan spokesman William J. Smith. Each charge carries a maximum seven-year prison term if she's convicted at trial.
