The suspect charged in two rapes, including the assault of a Towson University student, was caught after he filmed himself on a stolen cell phone he left at the scene of the second attack, police said.

Ian Murphy, 24 — who is charged with raping the 21-year-old college student days after he allegedly attacked a 22-year-old exotic dancer near the Inner Harbor  — filmed himself on a stolen cell phone about a day before the Towson crime, according to charging documents.
