Less than a year into the job, Bucks County District Attorney Michelle Henry has decided not to seek election next fall, the county's Republican chairman said yesterday.

"I talked to her about it," Harry Fawkes said. "She just said she wasn't going to run. Whether she's going to finish out the term or not, we don't know yet."

Henry, 40, the county's second female district attorney, could not be reached for comment. She was not in her office yesterday afternoon, and a message on her cell phone said she was not accepting calls.

Henry was selected Jan. 4 by the county's judges to complete the term of former D.A. Diane Gibbons, who had been elected to be a Common Pleas Court judge. At the time, Henry said she "absolutely" would run for a full four-year term in 2009.

Fawkes said Henry had told him of her decision early this week, but gave no specific reason. "She just felt that she was going to be doing something else, whatever that was," he said.

Henry, a native of Western Pennsylvania, is a 12-year veteran of the district attorney's office who formerly specialized in child-abuse cases. She was selected over at least eight other candidates in January, drawing praise from the county's judges for her intensity, fairness and work ethic.
