PHILADELPHIA — Marcellus Jones, the suspected killer of Beau Zabel, a teaching student from Austin who was gunned down for his iPod near the Italian Market nearly six years ago, was indicted Monday on murder charges.

A trial date has not been set.

The indictment, issued by a grand jury, means Jones, 35, already serving a life sentence for killing his suspected getaway driver, will stand trial for allegedly shooting Zabel once in the neck as he walked home from his night shift at a Starbucks in June 2008.

Beau Zabel moved from Austin to Philadelphia in May 2008, and was scheduled to start work in Philadelphia public schools.

The 23-year-old teaching fellow enrolled at Drexel had lived in Philadelphia for only six weeks before he was killed. Zabel — a 2003 graduate of Austin High School and 2008 graduate of Augustana College in Rock Island, Ill. — was just eight houses from his apartment when Jones and another man confronted him on a dark street in South Philadelphia.

Jones, according to a December arrest report, showed friends Zabel’s iPod shortly after the killing, saying he pulled the trigger because he was angry that he did not get anything more from the robbery.
