(Lexington, SC) -- Drug use may have hurt Timothy Jones' mental state.
A neuropharmacologist's pre-recorded testimony was played yesterday in Jones' murder trial in Lexington.
Jones has confessed that hekilled his five children in 2014, but he's asking jurors to find him not guilty by reason of insanity.
Jonathan Lipman testified that Jones used synthetic marijuana, which affected his mind. Lipman admitted, though, that he never met Jones.
