Apartment Robbed

Locked the apartment before we left, when we got back the front door was unlocked. Upon checking, 2 laptops, 1 HP 17 inch and 1 dell 15 inch, a sony nex c-3 camera and a gold ring was found stolen.

This is the 8th incident in the past 6 months in these apartments, all in the same manner with all the apartments losing the same things. Method of entry was the same as well, i.e., the open window of the maid bathroom and exiting through the front door.
