Boyfriend's admirer was detained for two days and has later left the village. The woman's brother was also investigated. From the link below:

Monribot said: “I was very very badly affected. I had to see a psychologist.” He said gendarmes had turned up at his house with search warrants on five occasions as they hunted for the murder weapon. Having been born in the village, he knows it better than most. Investigators wanted him to lead them to grottos in what proved to be a vain search.

Karen Carter was murdered right outside her home. One year on, clues are elusive

As a layman, I would say, it wasn't unjustified to suspect MLM and her brother. MOO
