Aaron Hernandez has marked his nearly one-year anniversary of being imprisoned on first-degree murder charges by getting a jailhouse tattoo that authorities are now trying to figure out the meaning of.

According to RadarOnline.com, the 24-year-old former NFL star is now sporting the tat "CBS/WBS IWBTG" on the back of his right hand. The website adds no one knows for certain what the inking means, but insists Hernandez was only spotted sporting it last week when he was arraigned on double murder charges stemming from a 2012, drive-by shooting in downtown Boston.

Aaron Hernandez arraigned on double murder charges

The former New England Patriots tight end has been jailed without bail since June of last year on first-degree murder charges in the execution-style killing of one-time associate Odin Lloyd.

Police have since speculated Hernandez may have killed Lloyd because of his knowledge about other violent crimes the former Florida star is suspected of having been involved in.

Aaron Hernandez tats hold clues in murder case?

Hinting that they might hold clues to some of the crimes he is accused of, authorities recently put out an all-points bulletin for any tattoo artist who worked on drawings dor Hernandez prior to his arrest in the Lloyd case.

Hernandez has pleaded not guilty in both cases and several media outlets have recently reported he may now be running low on cash and experiencing trouble paying off his team of high-priced attorneys.

Soon after his arrest last year, the Patriots voided the remainder of the five-year, $40 million extension he had recently signed with the team.
