Gun expert claims she received only 4 bullet fragments despite the total of 7 recovered from Charlie Kirk crime scene

There was a discrepancy in the number of bullet fragments given to an ATF investigator analyzing the rifle and ammunition recovered in the Charlie Kirk assassination case. 

Samantha Karner, a gun expert at the ATF, testified that she was only given four fragments to study despite a total of seven being recovered from the crime scene. 

Karner said she only found out a few months ago that there were originally seven fragments collected.
