CHICAGO -- A 20-year-old nursing student found dead last month in Chicago's Austin neighborhood was killed by a man she recently met online, according to Cook County prosecutors.On Jan. 23, prosecutors said Ehresman of Forest View drove to Chavez's Oak Park home, where a private surveillance camera recorded Chavez walking on the sidewalk about 10:40 p.m. and going inside with Ehresman.
Prosecutors said cell phone records showed the last call Ehresman made was to a number registered to Chavez and her phone's location records showed it"pinged" at his address on Jan. 23. While in police custody, Chavez made a phone call to his parents that was recorded in which he asked them to get his passport ready, prosecutors said.
