She called herself AngelEyez. That kind of relative anonymity makes some people far more willng to act in ways towards people they meet online that they would never consider with their neighbors, fellow church members, coworkers, etc. However, it's difficult to enter any chat forum on the net without getting something like that inquiry, from people who might well be your church deacon or copier repairman. Some of these interactions are not harmless. If someone sent you a letter via the post office describing his sexual fantasies towards you and said that he intended to get your children and husband out of the way so he could carry them out, the police would immediately be tracking the origin of the message, questioning and probably arresting the most likely sender, etc.
People get emails like that every day.
If they take a report, they don't follow up, or don't even know how to follow up. It's much easier to send threats that you know are illegal if you think those messages can't be traced. And all that adds up to why I encourage people to be very cautious about what information they make available online, about how open they are, and about how far they let net friends into their lives. I check into the backgrounds of people I meet on the net - in fact, I checked Sam out on the net before the relationship went anywhere. Without being a private detective or paying anybody for access to any databases, I knew where they'd lived together and apart and had read some of the fiction she'd published.
