About six months ago, police said an LIRR track worker discovered the remains of what appeared to be a middle-aged man. Although it was not initially considered a criminal case when the remains were discovered on Sept. 20, an extensive forensic investigation determined that the man died after sustaining several stab wounds to the torso, authorities said. He had been dead between two and eight years. The case has since been reclassified as a homicide and remains ongoing, according to authorities.On Friday, police released an artist's sketch of what they believed the man looked like, along with an accompanying description. Authorities said the man was believed to be Asian, between the ages of 30 and 35 and about 5-foot-5 inches tall.Authorities said the man was found wearing a black Tommy Hilfiger T-shirt with the name “Tommy” printed across the front, dark-colored jeans, leopard print underwear and brown and green work boots.Anyone with information on the murder or the man's identity should contact Crimestoppers at 1-800-577-TIPS. All calls will remain confidential.Overall, major crimes are down in the 109th Precinct from 2007, according to year-to-date NYPD statistics through March 9. By the beginning of last March, there was one murder. The precinct had six homicides in 2007.Reach reporter Stephen Stirling by e-mail at Sstirling@timesledger.com or by phone at 718-229-0300, Ext. 138.
