Authorities believe Aaron Hernandez's tattoos could somehow uncover answers about murders the ex-NFL star will be charged with next week.
"Prosecutors are asking for help from tattoo artists who may have inked Hernandez's right arm between February 2012 and June 2013," according to NECN.
The authorities are referring to a tattoo or tattoos on Hernandez's right forearm and a possible connection to a 2012 drive-by-shooting murder in Boston's south end.
Hernandez will be arraigned on murder charges related to the deaths of two men in that case, according to The Boston Globe.
Authorities wouldn't describe Hernandez's right-forearm tattoos or what kind of information they seek about them. And they say the tattoo artist or artists aren't suspects in the case - they're more like witnesses. But Boston station WHDH points out they might be tough to track down.
"During that time, Hernandez bounced around quite a bit - traveling from California to Connecticut, throughout south Florida and other parts and into Boston, Massachusetts, and Rhode Island as well."
In a separate case, Hernandez is also being charged with the murder of semi-pro football player Odin Lloyd. Lloyd's body was found in a North Attleborough industrial park in June of 2013, according to ABC.
The ex-Patriots tight end will be arraigned May 28 on charges related to the 2012 drive-by shooting.
