Police and witness give contradictory accounts of response to Texas mall shooting

Authorities have publicly denied the eyewitness account of a man who earlier had said he recalled the Allen, Texas, mall shooting scene immediately following the massacre in great detail, claiming he administered aid to victims before police officers arrived.

A gunman opened fire at the outlet mall outside Dallas, killing eight people and wounding seven others on May 6. 

Steven Spainhouer, a former U.S. Army officer, said he drove to Allen Premium Outlets after his son, sheltering in place inside the H&M store where he worked, called to tell him that he had heard gunfire on the property.
