Prosecutors say Jose Ibarra killed Laken Riley after a struggle, and data from Riley's smartwatch shows her heart stopped beating at 9:28 a.m.

An FBI special agent testified Monday that electronic location data seems to place Georgia nursing student Laken Riley and the man accused of killing her in the same wooded area at the time of her death. Meanwhile, prosecutors also played a recording of Ibarra being grilled by his wife about the case during a jail phone call.
