(CBS) Police are looking to talk to tattoo artists who may have inked the right forearm of former Patriots tight end and murder suspect Aaron Hernandez between February 2012 and June 2013, the Boston Herald reported.

Why is that? While nothing it clear yet, Deadspin wrote that it’s “reportedly under the belief that Hernandez may have gotten some ink to commemorate his role in the shooting.”

Prosecutors have accused Hernandez of playing a role in a 2012 double murder in Boston. He’s already awaiting trial after being charged with the 2013 murder of Odin Lloyd in a separate incident. The search for answers about his tattoos relates the to double murder.

From the Herald:

Investigators are seeking to speak with any tattoo artists who provided Hernandez with specific tattoos on his right forearm between February 2012 and June 2013 as witnesses in the ongoing homicide case, according to the Suffolk County District Attorney’s Office.

Authorities said they are not describing the specific tattoos or nature of the inquiry in the 2012 case in order to avoid tainting evidence.
