He is being held without bail and awaiting extradition to Pennsylvania in Colon’s murder. Colon’s family didn’t know what happened to her, as they lost all contact with her in late 1976 when she was eight or nine months pregnant with Sierra’s baby, said her niece, Miriam Colon-Veltman, on Friday. The young couple had an apartment together in Jersey City, New Jersey, where their families lived. But the apartment was abandoned when Colon’s family went to visit in mid-December and then they received a letter from Connecticut that she was happy, had the baby and was with her boyfriend, Veltman said.
