BOSTON -- Investigators asked for help from tattoo artists who may have inked former New England Patriots tight end Aaron Hernandez, saying they could help in the prosecution of a double murder Hernandez is charged with committing in 2012. Allen Bailey Jersey . The Suffolk district attorneys office stressed that the tattoo artists are considered witnesses, not suspects, and "may have made observations of evidentiary value." Hernandez is charged in three killings. He is scheduled to be arraigned May 28 on two counts of murder for allegedly shooting two men in Boston in 2012, prosecutors said Wednesday. Authorities have not said if there is any connection between those two slayings and the 2013 shooting death of Odin Lloyd, a semi-pro football player whose body was found in an industrial area near Hernandezs home in North Attleborough. Lloyd was dating Hernandezs fiancees sister. Hernandezs lawyers have said that their client looks forward to his day in court. He is being held without bail. Authorities said they hope to speak with the artist or artists who did specific tattoos on Hernandezs right forearm between February 2012 and June 2013. They didnt describe which of his tattoos they are referring to. Both of Hernandezs arms are covered with tattoos, and photographs of his right forearm show inked stars, words and other designs. "Were intentionally limiting our statements so as not to influence any potential observations by tattoo artists," said Jake Wark, a spokesman for Suffolk District Attorney Dan Conley. "We want unvarnished and unrehearsed information." Authorities specifically mentioned several places in their quest for tattoo artists: Hermosa Beach, California; Bristol, Connecticut; Palm Beach and Miami, Florida; Massachusetts; and Rhode Island. They stressed, however, that they are open to speaking with anyone anywhere who did tattoo work on Hernandez during the time period. Hernandez, 24, has been indicted on two counts of first-degree murder and other offences in the July 2012 killings of Daniel de Abreu and Safiro Furtado in Boston. A third man was wounded in that attack, while two others escaped unharmed. Hernandez and an associate had an "encounter" in a city nightclub with the victims before the shooting, prosecutors said. After the men left, Hernandez followed in an SUV and pulled up alongside the men as their vehicle was stopped at a red light, and opened fire, Conley said.
