The two men who were held in the Maria van Beek shooting were yesterday placed on a second identification parade but were again not identified.
The men who are already on station bail were subsequently sent away.
Police sources told Stabroek News yesterday that there have been no more arrests or new leads in the case.
However, investigators have said that they are still working assiduously to solve the brazen crime.
One of the suspects was held hours after the incident at a Georgetown location, while the other one was arrested last Sunday.
They were both released on station bail after they were not picked out in an identification parade held on Monday.
The police are still looking for the motorcycle that the shooter used to flee the scene. They know the colour but no one has come forward with any additional information.
