Hardly ever if at all.
How many killers have staged burglaries? A LOT! They mostly do a lousy job of it, but it is very common.
How many killers have staged multiple shot murders as suicides? Jeremy Bamber, ahd that´s it, as far as I know.
Staging a breaking competently when there is only 1-2 victims is actually not that difficult and no doubt has been successfully done. Doing it to kill more than 2 victims is a much more difficult proposition to achieve. To do it successfully you need to get a weapon that is not from the house (killing someone with a weapon from the house or worse a weapon people know you to have owned is stupid), actually break a window from the outside don't stage it by breaking it from the inside, shoot the victims out of bed unless there are 2 in the same room in which case it is ok if one is killed in bed, and ransack the place a little. The key is to make it look like you were a crook with a weapon, the home owners discovered you so you had to kill them because they could ID you and then flee. Some crooks will kill then stay an extended time stealing things others flee with little to nothing.
Going room to room to kill non-witnesses in bed before fleeing is not something crooks do so that is one problem with if you want to stage mass killings as a burglary gone wrong. Jeremy was too cheap to even buy an extra rifle magazine (which would have helped immensely) let alone to get a different weapon to support a burglary gone wrong scenario. The scenario he came up with was superior to a burglary gone wrong he simply failed to stage it as good as he could have/needed to.
I have the knowledge to cover all bases in staging a crime but there are 2 variables that can't be accounted for:
1) will I actually be able to remember everything I need to and be able to do it without messing up.
2) the other variable is others. Victims can end up doing things that mess things up and even third parties who end up by chance being a witness in some way or even stopping by the wrong time by dumb luck. A crime at night minimizes third party interference and likelihood of being seen hence why it is a choice time but plenty like daytime burglaries when they expect people to be at work and no one home.
Even the best plans though can be tripped up by something simple like a guy you buy an illegal gun from ratting you out at some point. There is rarely no strings dangling that can end up screwing you and now with DNA and other analysis of evidence available it is harder than ever to avoid liability. Even dog hair and plant evidence have ended up catching criminals.
Rational people realize they are likely to get caught and not going to do it people who are convinced they are smarter than everyone else usually resort to crimes and fortunately they virtually always are wrong about being smarter. Someone truly smart avoids crime.
