Avalanche debris in the Hotel Rigopiano.

Italian prosecutors are seeking a trial for 25 suspects in connection with the 2017 avalanche at a resort hotel in the Italian Apennine mountains that killed 29 people.

The Italian news agency ANSA is reporting that prosecutors formally requested trial indictments against 24 people and the hotel company. Accusations include multiple counts of manslaughter and causing a disaster.

The avalanche that smashed into the Hotel Rigopiano in Farindola occurred on Jan. 18, 2017. Among the dead were both guests and staff.

The investigation has largely focused on why help was so slow in arriving, why the hotel was not evacuated after a heavy snowstorm and if it had authorization to be built in an area known to be prone to avalanches.
