Four witnesses have invoked their Fifth Amendment rights against self-incrimination and refused to testify in a Houston fraud and conspiracy trial.
Meanwhile, a former Merrill Lynch executive testified he can't remember or never saw certain documents that made a loan – appear to have been a sham.
William Fuhs was on the stand in his trial stemming from a year-end 1999 deal with Enron.
Houston-based Enron filed for bankruptcy protection after its stock collapsed in 2001.
Fuhs is one of four former Merrill executives and two former Enron executives charged with pushing through a loan purported to be a sale.
The case involves interest in three power-generating barges off Nigeria.
Fuhs wrapped up his defense yesterday.
Defendant Dan Boyle, who's a former finance executive at Enron, began testifying late -- but has yet to get into the mechanics of the deal.
