The suspect then drew a silver handgun and demanded that the victim give him all of his money. victim complied and the suspect, who was also wearing a hat, and a green jacket fled the scene. The victim also described the suspect as very well spoken or educated.

Cambridge Police also report that a suspect with an armed robbery occurred around 8:00 p.m. on March 4 in front of 32 Shepard St.
