I’ve seen different reports. Either anchored off Grand Anse, or at a “St.George’s marina”, which would most likely be Port Louis? I guess it could have been at the yacht club, but Port Louis seems more likely for transient dockage.

Based on the most recent information they were at a marina, not anchored. Having been involved in scores of murder investigations, I always caution that media reports (even from official sources) are often incomplete or inaccurate. It generally takes a few weeks to filter through all the available evidence to gain an accurate account of what happened.
