Luis Sierra, 63, was arrested on Wednesday for the murder of Evelyn Colon, 15, which took place 44 years ago.
Colon’s remains were found in three separate suitcases along the riverbank of the Lehigh River in Carbon County, Pennsylvania in 1976. Her remains were discovered along with those of her almost full-term fetus.
Colon was 15 when she was murdered. Colon and Sierra, who was 19 at the time, were in a relationship and living together in Jersey City.
