Albenga, September 6 - An appeal date has been set for September 27 in the case of an Italian couple serving a sentence of life in prison for the 2010 murder of their travel companion. On Tuesday, the Indian Supreme Court was forced to postpone appeal proceedings for Tomaso Bruno and Elisabetta Boncompagni when the prosecutor failed to show up in court. The couple has been convicted of killing their friend Francesco Montis during a holiday in the Hindu temple city Varanasi in Uttar Pradesh. The fathers of the two defendants had been dismayed by Tuesday's postponement in the case, which is being closely followed by the Italian ambassador in New Delhi, Daniele Mancini, and his staff. The High Court of Allahabad had rejected Bruno and Boncompagni's petition for an appeal last October, but hopes were raised in February when the Indian Supreme Court accepted the request for appeal. Indian authorities arrested and tried Bruno, who is from the northern town of Albenga; and Boncompagni, from Turin in February 2010 after discovering their travel companion, Francesco Montis, dead in a hotel room the three had been sharing in Varanasi. Montis was found strangled in what investigators said was a "love triangle" gone wrong.
