Duggar, 33, is charged with receiving and possessing child pornography and faces up to 20 years in prison on each count if convicted.
Under questioning by Duggar’s lawyers, forensic computer analyst Michele Bush said the computer where child pornography was downloaded could have been accessed remotely.
The defence has argued that someone else downloaded or placed the child pornography onto the computer at Duggar’s workplace, noting that no child pornography was found on Duggar’s phone or laptop.
Josh Duggar pleads not guilty to receiving, possessing child porn.
But when challenged by prosecutor William Clayman on how many times she had testified in a federal criminal court case, she first said she would have to check her resumé, then admitted under follow-up questioning that the Duggar case might be her first, the station reported.
Prosecutors say child pornography was downloaded to the computer in May 2019.
