The man accused of killing eight and injuring seven others at an outdoor mall in Texas had researched the busiest day to carry out his brutal massacre.
Mauricio Garcia, 33, of Dallas, had posted photos on social media in mid-April of a store at the Allen Premium Outlets in Allen, Texas, near where he shot and killed unsuspecting shoppers in broad daylight on May 6. Allen is about 25 miles north of Dallas, in Collin County.
