Swiss prosecutors summon owners of ski resort bar after deadly blaze

Switzerland - Swiss prosecutors summoned on ​Friday the owners of a ski resort bar where a fire on New Year's Day killed 40 people, amid growing criticism that the couple ​is still at large.

The prosecutors are investigating the French owners on suspicion ‌of crimes including homicide by negligence, while victims' ⁠families have filed legal ‌complaints over the blaze at the "Le Constellation" bar in the town of Crans-Montana.

The owners, Jacques and Jessica Moretti, did not answer reporters' questions as they entered the prosecutors' office in the nearby town of Sion on Friday, ​which Swiss authorities have designated a national day of mourning over the tragedy.

The couple have expressed their grief over the fire and said they would cooperate fully with ‌the investigation. ‌More than half of the 40 people killed in the blaze were teenagers and a further 116 people ⁠were injured, many of them seriously.

"We are devastated and overcome with grief, our thoughts are constantly with the victims, their loved-ones who have been bereaved so brutally and ⁠prematurely, and all those who are fighting for ⁠their lives," they said in a January 6 statement.

Prosecutors ‌said last weekend that the legal criteria to detain ‌the couple had so far not been met.

Witnesses and prosecutors have said the blaze appeared to have been started by the use of ‍sparkling candles that set foam soundproofing on the basement ceiling alight.

Questions remain about oversight at the bar, which the local mayor admitted this week had missed multiple safety checks.

Twenty-one of the dead were from Switzerland, seven from France, and six from Italy. There was also a Swiss-French dual national and a French-British-Israeli national.

The presidents of France and Italy are expected to attend Friday's ​ceremony in the nearby ‌town of Martigny to mark the tragedy and remember the victims.
