Swiss authorities found a dead British woman in a hotel bathroom and the police were still investigating the incident.
The Swiss woman's husband, a 29-year-old German, has been detained by the Swiss authorities for questioning, the Times reported Friday. The suspect is suspected of being the culprit, especially after wounds and fractures were found on his girlfriend's body.
According to local reports, prosecutors opened an investigation into the murder last Tuesday, just one day after the men and the girl entered the hotel at the foot of the Alps.
"There was a lot of disagreement between the couple on the night before the woman was found dead," one of the hotel staff said, "other guests complained of their high voice and one of the staff went to try to calm the situation."
The girl's friend arrived at the hotel reception at 6:30 am, in a tense state, to tell the staff that his girlfriend was suffering from health problems. The hotel staff summoned the paramedics, who announced her death at the scene.
According to local press, the couple had a "strong" relationship. Reid lived in Berlin and spent some time in Vietnam, according to her social networking pages.
