COLLEGE STATION, Texas — "Mysterious Dolphin" needed an emergency contraception pill dropped off on a porch outside of town.
Allison Medulan, a sophomore at Texas A&M University who had just come from biology class, saw the request on her cellphone via an anonymous text hotline. She gathered a box of the one-dose contraceptive, a pregnancy test, and a few condoms from her apartment and headed over. Inside a bewildering development of modest townhomes, Medulan tucked the plastic delivery bag next to the doormat.
