Entertainment TV Prosecution Gets Heated Questioning Josh Duggar Relative and Colleague: 'You Were Hiding Something' Josh Duggar has been accused of receiving and possessing child sexual abuse material By Ally Mauch and Adam Carlson Published on December 2, 2021 04:00 PM Share Tweet Pin Email Day three of Josh Duggar's child sexual abuse material trial grew tense when witness Matthew Waller took the stand. Waller was a former colleague of Duggar's at Wholesale Motorcars, a used car lot Duggar owned and operated in Arkansas. Waller is also a relative of the 19 Kids and Counting alum — his brother David Waller is married to Priscilla, the sister of Duggar's wife, Anna. Duggar, 33, has been accused of downloading files depicting child sexual abuse on May 14, 15 and 16 of 2019 on the desktop computer at Wholesale Motorcars. He has pleaded not guilty to the charges against him. His defense has suggested other people with access to the office computer were really responsible and Duggar was railroaded. During his opening argument on Wednesday, Assistant U.S. Attorney Dustin Roberts alleged that Duggar had installed a password-protected Linux partition on the computer, which effectively split the hard drive in two, and that the child sexual abuse material was found on the partitioned part.

The prosecution said the partitioned part of the hard drive had a different password from the main operating system, one that Duggar allegedly used for other personal accounts and that included his birth year, Intel1988. On Thursday, Waller testified to working for Duggar from late January through April of 2019, selling cars and doing some mechanical repairs and detail work. When questioned first by Roberts, Waller said there were occasionally others at the car lot but that he and Duggar were the only ones working full-time during his employment and he only ever saw him and Duggar using the keypad to get into the office, where the desktop computer was located. Waller also told Roberts that he didn't ever give the main computer password — which he said he has since forgotten — or office keypad code to anyone else. Josh Duggar.

"'Intel' very faintly rings a bell," Waller replied — testimony that, if accepted by the jury, would bolster the defense theory that other people also had access to the office computer's partitioned side. Roberts soon got up to redirect, telling Waller in a raised voice, "I told you I thought you were hiding something, didn't I?" "I asked you specifically if you were intending to testify to something that you were not telling me," Roberts added, indicating that Waller previously said he didn't know the password. Josh Duggar.

"If you know what I mean," he added, to which Roberts said, "No sir, I don't know what you mean." Defense attorney Story then got back up to ask Waller if he remembered the government asking him about the password before. "It's hard to remember who are the government lawyers and who are the defense lawyers ... I'm just starting to get it straight," Waller said. Story asked whether the defense simply instructed him to tell the truth on the stand, and Waller said yes.

When he repeated that "the word 'intel' was vaguely familiar," Roberts asked where he first heard that, because the government never mentioned it in their questioning before the trial. Waller admitted that the defense was the one who brought it up, so Roberts asked if the defense had told him information he didn't otherwise remember. Waller replied yes — drawing a scornful laugh from Roberts. The back-and-forth continued, with Story getting up to ask Waller whether the defense team gave him information outright or he was simply asked questions during the pre-trial prep. Waller said the defense only asked questions. "When we asked if it [Intel1988] meant anything it seemed to ring a bell," Story said, and Waller responded, "A vague bell."

Danny Johnston/AP/Shutterstock Roberts stood up for another round of questioning, though the judge told him at this point, "Mr. Roberts, we can only beat this horse so many times." Noting that he only had one more question, Roberts repeated Waller's earlier testimony that he didn't remember the password to the main computer. Waller confirmed this, and said he would use a sticky note Duggar pasted on the computer in order to remember it. Roberts finally asked whether he ever heard Duggar mention the specific password for the partition, Intel1988, around him, to which Waller said he didn't recall.
