You're not going to find any link to a statute that holds landlords liable for criminal acts by a third party because there isn't any such statute.
This situation would fall under what is known as "warranty of habitability." Your landlord is required to take reasonable measures to ensure health and safety of the tenants. If your landlord knowingly allows gangs and criminals to congregate on the premises, if your landlord fails to provide working locks on your doors and windows, if your landlord does not have adequate lighting then they might be liable. If, however, they have met these conditions and someone still steals your property, breaks into your home, etc. you can not reasonably argue that your landlord is liable. He did not do anything grossly negligent and did not know this would occur but failed to take reasonable measures to prevent it, and he did not fail to provide you with reasonable security measures as provided by law.
You had a bit of bad luck. Nothing you can do about that. Get renters insurance.
