Allen, Texas, shooting victims: What we know about the mall attack so far

Families and officials are releasing the names of the eight people killed at a Texas mall Saturday by a gunman, who authorities identified as Mauricio Garcia. A police officer who was at the mall in Allen for an unrelated call killed the shooter, officials said.

Two young sisters, Daniela Mendoza and Sofia Mendoza, died in the rampage at the Allen Premium Outlets mall, according to a message to families from Superintendent David Vinson of the Wylie Independent School District. Daniela Mendoza was in fourth grade and Sofia Mendoza was in second grade at Cox Elementary in Sachse, Vinson said.

Principal Krista Wilson described the girls as "rays of sunshine," according to Vinson. Their mother, one of the seven other people hurt in the shooting, was in critical condition, the superintendent said.
