A man already serving a life sentence in one murder case will be heading to trial in the shooting death of an aspiring teacher who authorities say was gunned down for his iPod a month after moving to Philadelphia.



Prosecutors say an indicting grand jury charged 35-year-old Marcellus Jones on Monday with murder, conspiracy, robbery and other counts in the May 2008 murder of 23-year-old Beau Zabel.



Authorities said Zabel had moved from Austin, Minn., and was scheduled to start work in the public schools.



Jones was convicted earlier of killing a man police said was the getaway driver in the Zabel killing.



The Philadelphia Inquirer reports that prosecutors presented the new murder case to a grand jury rather than in open court because of concerns about witness intimidation.
