At least eight people have been killed and seven others injured in a shooting at a mall in Allen, Texas. Reports suggest that one of the shooters was wearing tactical gear and is believed to have been the only one to fire shots before being shot dead by a police officer. Witnesses said they saw what appeared to be a police officer and a security guard unconscious on the ground. There are reports circulating online that suggest there may have been a second shooter, however, this has not yet been confirmed by authorities. The vehicle of the deceased suspect has reportedly been identified and is being examined by the bomb squad. This latest mass shooting follows a spate of recent gun violence, which has prompted calls for tighter gun control legislation. Texas Governor, Greg Abbott, has offered support to local officials and emergency services.
