The Suffolk County sheriff was back on the witness stand Tuesday in the trial of Suffolk's powerful Conservative Party leader.

As News 12 has reported, Ed Walsh, who recently retired as a lieutenant for the sheriff's department, is accused of falsifying timesheets and illegally collecting more than $200,000 in pay for time he did not work.

Prosecutors say Walsh was instead golfing and gambling, and attending functions for his role as Conservative Party chairman. Walsh's defense says he had been working, and was working outside the office because his position was as a liaison.

On Monday, Suffolk Sheriff Vincent DeMarco testified that Walsh's former duties did not require him to work outside the jail. He was returning to the stand Tuesday for cross-examination. Defense attorney William Wexler grilled DeMarco, saying he must have known that Walsh was doing work outside the jail as a liaison, even saying the two had hundreds of phone calls during off hours.

Prosecutors also asked DeMarco about allegations made against Walsh in 2012. Although the judge did not allow DeMarco to say what those accusations were, the sheriff did say, "We requested certain pieces of evidence from the Suffolk Police Department and district attorney's office." He added that he never got the evidence and therefore could not discipline Walsh or fire him.

Taking the stand after DeMarco late Tuesday afternoon was Richard Schaffer, the Democratic Party chairman for Suffolk County. He told prosecutors about numerous times he attended events with Walsh, some of which were during hours Walsh was scheduled to be at the jail.

Federal prosecutors say they have 10 more witnesses on call and plan to rest their case by the end of the week.
