Found this from a PA attorney (writing in general) - if there was a previous murder on the property, Pat's may be liquidated...
Negligence or carelessness is the failure to use the ordinary care that a reasonable person would have used under the circumstances. In the context of a Business being sued for a criminal act occurring on its premises, a business owner has a duty to use reasonable care to fund out if a customer is being harmed or is likely to be harmed on the premises and to warn or protect the customer.
To prove Negligence in the context of a crime occurring on a Business property, the issue is whether the business owner knew or should have known that there was a likelihood of criminal activity occurring on the property and whether the business took reasonable steps to warn or protect the customer against it. In deciding the issue of Negligence, the location and nature of the business, as well as past experiences, are relevant.
Using those factors as a guide, the more potentially dangerous the location and business type are (like a rough neighborhood bar in a sketchy Philadelphia neighborhood) and the more prior history of crime occurring at the Business there is, the more likely it is that the Business will be held legally responsible for injuries from crime if it did not undertake appropriate safety and security procedures.
This is part of the reason why you see security cameras, security guards and metal detectors being more common at Pennsylvania businesses. Businesses want to prevent injuries to customers, but they also want to avoid legal liability by establishing that they took reasonable steps to make the Business safe and secure.
