An Ulster County woman, already jailed in a string of alleged burglaries in seniors' homes, now faces forgery charges in connection with a bad check at a gas station -- again in an attempt to victimize an elderly person, police said.

Brigit L. Conroy, 26, of Old Stage Road in Saugerties, was arrested Wednesday at the Ulster County Jail and charged with second-degree possession of a forged instrument, a felony; and third-degree forgery, petty larceny and fraudulently obtaining a signature, misdemeanors, the Ulster County Sheriff's Department said Saturday.

A report of a bounced check at Saugerties Sunoco in the Barclay Heights hamlet launched an investigation, which determined that Conroy had forged a check from an elderly Saugerties woman with whom she had arranged to work as a home health care aide, police said.

It was Conroy's second arrest of the week. On Monday, Kingston police charged her with burglary and possession of stolen property, among other charges, alleging that she had posed as a home health care aide to gain entry into numerous senior residences in the city and clean out their cash and jewelry.

Conroy was arraigned in Saugerties Town Court and returned to the jail in lieu of $5,000 cash bail or $25,000 bond. She is due to return to court Monday at 7 p.m. No further information on her court appearance or legal representation was available Saturday.
