Analyst testifies after Simpson trial gets late start

LAS VEGAS, Nevada -- The third day of trial for O.J. Simpson and his former golfing buddy, Clarence "C.J." Stewart, got a late start this morning, as the court was forced to wait for late jurors to arrive.

It's the second day proceedings have been delayed because of tardy jurors.

Simpson, 61, and Stewart, 54, both are charged with a dozen robbery, weapons and kidnapping-related offenses. The charges stem from a run-in with two memorabilia dealers, Alfred Beardsley and Bruce Fromong, in a Las Vegas hotel last year.

Once the 18-member panel of jurors and alternates was seated at 8:40 a.m. this morning, Judge Jackie Glass resumed the video testimony of FBI audio analyst Kenneth Marr.

Marr was unable to testify in person because of travel arrangements and commitments that were made prior to him being asked to attend court. He was cross-examined three weeks ago, on Aug. 25.

The jury heard the first 30 minutes of his testimony Tuesday before Glass adjourned for the day. Jurors have another 90 minutes of video to watch today before the prosecution calls its next witness.

In his testimony, Marr explained the process he used to inspect the audio files earlier this year, and what he found when he examined them.

"I was not able to determine whether or not the files were altered," he said. He did, however, say the recoding included several areas where "over-recoding" was found.

"There was other audio underneath that audio that I can see," he said.

After Marr's account concludes, jurors expect to hear from Las Vegas police officer Andy Caldwell. Thomas Riccio is expected to take the stand after Caldwell.
