Over several months, students tracked down murder victim Concepcion Diaz’s wife, Manuela Avalos, overcoming the difficulty of finding someone who went by a different first and last name in court documents. During an interview with students, Avalos said she did not remember writing a victim-impact statement where she asked the judge to sentence Ariel Gomez to the maximum penalty. In addition to Avalos’ story, students also profiled Gomez’s wife, Ivette Ginjauma, who married Gomez while he was in prison. Read the full story here.

That same detective has been accused of manipulating witnesses and coercing confessions in dozens of other cases. Read the full story here.

Students tracked down key eyewitness, a known drug addict who gave conflicting statements about the night of the crime. Read the story here.
