The man US authorities have publicly named as a suspect in the fatal shooting of Jam Master Jay has denied any involvement in the murder, accusing cops of trying to pin "all the blood in rap" on him. Federal authorities in the US believe Ronald 'Tinard' Washington is one of two men responsible for the death of the Run D.M.C. founder, born Jason Mizell, who was gunned down in his studio in Queens, New York, on 30 October, 2002. Washington was named as a suspect after his ex-girlfriend Daynia MCDonald claimed he had confessed his involvement in the 2002 shooting to her. He is also said to have admitted taking part in the 1995 murder of Randy 'Stretch' Walker, a close associate of the late rapper, Tupac Shakur. He was implicated in Mizell's murder in a letter by authorities to the judge presiding over his recent (Apr07) trial for armed robbery in Brooklyn, New York. Prosecutors Sean Haran and Adam Abensohn wrote to Judge Nina Gershon, alleging Washington and an unnamed associate entered the producer's studio and "pointed his gun at those present, ordered them on the ground and provided cover for his associate to shoot and kill Jason Mizell." But Washington, who was convicted on 5 April (07) for his role in six armed robberies in November 2002, has protested his innocence in the killings and says his ex-girlfriend is "making up lies" in her bid to avoid deportation. He says, They want to blame me for all the blood in rap. They are trying to pen me up for these murders. "It's all lies. (MCDonald's) telling them that I was mad at Jay because he was doing better than I am, that I killed Stretch because he owed me something and I wanted it. She is making up lies because they threatened to deport her."
