Inquirer staff writer Craig McCoy reports:

Two of the investigators who built the federal case against former State Sen. Vincent J. Fumo may take the stand against the state senator in his corruption trial today.

Former FBI agent Kathleen T. McAfee and IRS agent Robert Tengood are tentatively scheduled to testify. McAfee, who is now first deputy inspector general for the City of Philadelphia, was a key agent in the case, along with a colleague, FBI special agent Vicki Humphreys. McAfee is expected to talk about the probe into Fumo's free yacht cruises on yachts owned or leased by the Independence Seaport Museum. Fumo was a board member of the museum.

Humphreys is expected to testify also, towards the close of the prosecution case.

Tengood helped in the probe as well, which focuses in large part on a nonprofit, Citizens' Alliance for Better Neighborhoods, once led by a top Fumo aide, Ruth Arnao. She is now Fumo's co-defendant in the trial.

The day may include testimony from other witnesses. Arthur Amelio, an accountant who had reviewed Citizens' Alliance's books, is expected to resume the stand at the start of today's trial proceeding.
