NOXVILLE, Tenn. (AP) — A series of texts sent to a 16-year-old Tennessee girl two nights before she was shot to death in her bed have surfaced in the trial of her former boyfriend. Prosecutors contend the texts were part of a plan by former Division III college football player William Riley Gaul to lure Emma Walker outside a house where she was visiting friends in November 2016. The now-19-year-old Gaul is on trial on charges including first-degree murder and especially aggravated stalking.
