Prince George's County police will spend Monday morning walking the same street that Marckel Norman Ross used to take to Central High School before he was gunned down in September.

Ross, 18, was shot to death on the 6100 block of Old Central Avenue on Sept. 11 at about 6:50 a.m. while on his way to school.

Police are still looking for suspects and will be talking with pedestrians and commuters between 6 and 8 a.m. along Old Central Avenue in Capitol Heights on Monday in an effort to find an unidentified citizen who police said might have been robbed in the area prior to Ross' murder.

Police said they believe the robbery victim did not report the crime, and they would like to speak with the victim.

It's unclear what connection the robbery might have with Ross' murder.
