The TVTropes Trope Finder is where you can come to ask questions like "Do we have this one?" and "What's the trope about...?" Trying to rediscover a long lost show or other medium but need a little help? Head to Media Finder and try your luck there. Want to propose a new trope? You should be over at You Know, That Thing Where.
For the murderer, it'd be Refuge in Audacity.
Can also be Last Disrespects, as they don't show proper Due to the Dead by being civil for at least the duration of the service. (IE, attacking a rival mob boss is Nothing Personal, attacking him at his mother's funeral is a blatant insult)
A common example of something that's likely to set up Even Evil Has Standards, too.
^^ How so?
^Because people go to a funeral to pay their respects, not to commit violent crime, especially if the killer was responsible for the death of the deceased. That's not only brazen on the killer's part, it's insult on top of injury.
Even the most hardened criminals wouldn't go that far just to spite someone. But in the above scenario, the killer has no such reservations. They killed the first victim, then show up their funeral to commit another murder with no regard for the witnesses present.
^ That's covering the audacity part but there is no refuge. It would require some kind of pressure on the murderer to commit the crime there and then.

^No it doesn't. Refuge in Audacity simply means that the perpetrator doesn't care about any potential consequences of whatever act they're committing. Hence, the audacity is their refuge (i.e. "So insane, that it's impressive.")
Just as Lupin III (Interpol's most wanted thief) once broke into a police station while on-duty officers were present. Then topped that by having sex with Fujiko (who's an international jewel thief) in the police station's file room without getting caught. The cops never knew the guy they were looking for was right there.

Is there a trope that describes when a fight or even murder happens at a funeral? I've combed through the list of funeral tropes and didn't find something like that.
