Father Leo Heinrichs, O.F.M. (August 15, 1867, Oestrich, now a part of the city Erkelenz, Germany - February 23, 1908, Denver, Colorado) was a German-born Roman Catholic priest of the Franciscan Order. While assigned at St. Elisabeth of Hungary Church in Denver, Colorado, Heinrichs was shot dead while distributing communion by a Sicilian anarchist. Joseph Heinrichs was born on August 15, 1867, in Oestrich, now a part of Erkelenz, Northrhine-Westphalia, Germany. After fleeing Germany's Kulturkampf, the Franciscans settled at St. Bonaventure's Friary in Paterson, New Jersey, where, on December 4, 1886, Heinrichs received the Franciscan habit and the name Brother Leo. He took his final vows on December 8, 1890, and became an ordained priest on July 26, 1891. Between 1891 and 1907, Father Leo served in various positions in the New York and New Jersey area including pastor at Holy Angels parish in Singac (Little Falls), New Jersey, at St. Stephen's in Croghan, New York, and at St. Bonaventure's. During a smallpox epidemic while he was pastor at Paterson, Father Leo was known to spend many hours at a nearby “pest house” ministering to the sick and the dying.
