A longtime Saratoga County assistant district attorney who became a central figure in the corruption case against former Halfmoon Supervisor Melinda Wormuth on Tuesday night became the “full-time” town attorney, a job that will pay her $150,000 year.

The Town Board unanimously approved a resolution to increase the duties of Lyn Murphy, who had been paid more than $95,000 a year by the town as a part-time attorney working 17.5 hours per week. In the new position, Murphy will work 30 hours per week and take on a broader role, including personnel work, according to a person briefed on a town managers meeting Monday when the hiring was announced to department supervisors. Murphy is slated to start the job on Oct. 1 and will no longer work as a full-time assistant district attorney.

“The town is growing immensely, and we do need a full-time attorney on staff,” Supervisor Kevin Tollisen said. “This is in the best interest of the town.”

Reached by phone prior to the vote Tuesday, Murphy said she would accept the additional hours with the town, but would not comment on whether she would quit her county job.

Murphy makes $91,990 as an assistant district attorney and $95,346 as a part-time town attorney for a total of $187,336, according to the Empire Center, an Albany think tank that promotes public policy reforms. In a report last year, Empire Center said Murphy is one of the top-paid local government employees in the state.

Murphy’s dual roles became an issue in the recent prosecution of Wormuth, who claimed Murphy told her it was not a conflict of interest to lobby on behalf of the mixed martial arts industry in exchange for money. But the undisclosed lobbying work turned out to be an undercover FBI sting.

Last month, Wormuth pleaded guilty to felony charges of extortion and lying to federal agents. She also pleaded guilty to stealing $6,000 from a campaign account.

Murphy, whom Wormuth described as a close friend, was expected to be called as a witness if Wormuth took the federal case to trial.

District Attorney Karen Heggen on Monday declined to comment on Murphy’s new job except to say that she was still employed as an assistant district attorney.

Tollisen said Murphy’s salary was based, in part, on her rate of pay for a 17.5-hour week.

“We need someone here on staff on a regular basis,” the supervisor said. “There’s a number of different items the town faces every day — litigation, town court matters, grants we’re working on. There’s a genuine need for our town attorney to be full time.”
