If Judge Judy has taught me anything, its that stupid people somemtimes do stupid things with some kind of backstory.
Cousins aunties step-brothers mothers dog probably borrowed money a while back, or stepped on someones shoe or called someone a slag.
Anyway point is, if there was some sort of personal involvement or the victim recognised them from kindergarten or if it was some sort of vigilantism (sp) the news/police report isnt going to mention it.
Forced break-in of elderly lady? sure, probably pretty straight forward.
Man stabbed in a supposed mugging and the muggers not taking anything and then being caught within 24 hours? theres probably more to this.
