New Liturgical Movement, Gregory DiPippo: One of the most unusual true stories in the annals of Catholic hagiography is that of Bl. Carino, the assassin of the Saint whose feast is traditionally kept today, Peter the Martyr. Carino was one of the two men hired to kill Peter for his work against the Cathars, as he was traveling in the area of Milan; the other, Albertino, fled in fear at the moment of the attack, and it was Carino who dealt the martyr his death-blow with a knife to the skull, and fatally wounded his companion, brother Dominic. Carino was taken to Milan, where he would certainly have been tried and executed, if not lynched by popular uprising beforehand; the mayor of the city, however, was involved in the plot against St Peter, and arranged for Carino’s escape.
