Police discredit witness in Texas mall shooting aftermath

Police in Texas have disputed the account of a witness who described in detail the aftermath of a deadly shooting at a shopping mall. Steven Spainhouer had told US media outlets he arrived at the Allen Premium Outlets near Dallas before first responders and gave medical aid to victims. However, police said they had determined he was not credible and that there were inconsistencies between his public accounts and the facts established in their investigation. A gunman killed eight people and injured seven others in the attack on 6 May.
