HOUSTON -- Prosecutors in the trial of fired TSU president Priscilla Slade said they are close to calling the last of their witnesses and almost finished presenting their side of the evidence, KPRC Local 2 reported Monday.

That could mean that the jury will soon hear closing arguments in the case.

Defense attorney Mike DeGeurin told reporters that he might not call anyone to testify for the defense.

"If they rest tomorrow and I feel there is no benefit to put anything on, I will not put anything additional on," DeGeurin said.

Slade's attorney said he does not believe the state has proved its case.

"The jury has been here four-and-a-half weeks, and the state has put on everything they could from 1999 to 2007. That's a lot of information and if that's not enough then there won't be anymore case," he said.

DeGeurin also said that no decision has been made on whether Slade will testify.

Meanwhile, prosecutors who have already called nearly 20 witnesses continued to try to prove that Slade knowingly and intentionally misspent university money. On Monday, the director of TSU's procurement services testified that out of dozens of expenditures submitted by the former president, only a handful of the requests followed proper state and university guidelines.

Prosecutor Donna Goode asked Alice Roseman, "Why did you process the paperwork if you knew it was wrong?"

Roseman said it was because she felt pressured, and Slade's assistant told her Slade didn't want to get her staff involved and wanted to keep everything confidential.

The head of Texas Southern's purchasing department also took the witness stand. Wanda Pleasant told the jury that after purchase order modifications for landscaping, furniture and a security system crossed her desk, she began to realize that the expenditures were for Slade's personal residence and not for the university.

Pleasant testified she thought to herself, "OK, here we go again" when she saw a requisition for a backyard fence.

But in cross-examination, DeGeurin tried to show that the alleged questionable expenditures were things that had been done in the past and that there was a precedent for it.

"The processing of the paperwork that was not done by Dr. Slade, there was no intent to do anything wrong," DeGeurin said. "They were the type and nature of expenditures that a board would approve if brought before them."

Prosecutors called TSU general counsel Gita Bolt as the last witness on Monday.

Slade is charged with felony counts of misapplication of fiduciary property. If convicted she could face punishment ranging from probation to life in prison.
