The trial for the man suspected of killing Prince George’s teen Marckel Ross in September, 2012 has been delayed until May, 2014. Travon Donnell Bennett, 20, has been charged with first-degree murder, robbery and other related crimes and his trial was set to begin Monday morning.

Police believe Bennett was attempting to rob Ross during the junior’s 1.5 mile walk to school in Capitol Heights.

The shooting rattled Prince George’s County, as Ross was the second of six high school students killed over a six-month period between late 2012 and early this year. The youngest teen who died was 14, the oldest two, including Ross were 18.

Ross left his Prince George’s County home early the morning of Sept. 6, 2012 to walk to Central High School, but the 18-year-old never made it to class. Instead he was found lying on the sidewalk, shot in the chest.

After an investigation, police filed charges against Bennett when detectives linked a gun used in a different robbery Bennett was allegedly involved in to the same weapon that killed Ross. Police arrested Bennett less than two months after Ross’s death on an unrelated robbery charge.
