ATHENS, Ga. (AP) — Testimony resumed Monday in the trial of the man accused of killing Georgia nursing student Laken Riley, a case that became a flashpoint in the national debate over immigration during this year’s presidential campaign.

In the nine months since Laken Riley was killed while jogging at the University of Georgia, her death turned into a lightning rod over crime and illegal immigration and cast an ominous shadow over the college town of Athens.

Jose Ibarra, who entered the U.S. illegally​, is charged with murder in the February killing, which helped fan the immigration debate during this year's presidential campaign.
