A tattoo artist who worked on NFL star turned convicted killer Aaron Hernandez is scheduled to testify at his upcoming murder trial.
Tattoo artist David Nelson is expected to tell the jury about tattoos of a gun and the words "God Forgives" on Hernandez.
Prosecutors believe the tattoos are an admission of guilt to the killings of two men in a 2012 South Boston drive by shooting.
Nelson is one of 19 expert witnesses listed by the prosecution for the upcoming trial.
