Both emotional and technical testimony today in Alex Murdaugh's murder trial.

The day started with Alex Murdaugh's defense lawyer grilling ballistics expert Paul Greer  Greer testified older shell casings found on the Murdaugh's estate and those found near Maggie Murdaugh's body were shot by the same weapon. 

Defense lawyer Jim Griffin Greer challenged the testimony on the accuracy and creditability of what he called the "subjective" techniques used in firearms examinations.

Alex Murdaugh's former best friend, Chris Wilson, shed tears as he recounted how Alex Murdaugh asked for money as allegations of financial crimes came to light. Wilson also testified that Murdaugh admitted to opioid addiction.
