Aime Alvarado Salinas, 47, died from a single gunshot to the head, according to Dallas police. The woman's body was found on Friday, inside her Dallas residence, after Alvarado Salinas' own parents contacted authorities, requesting a welfare check for their daughter, who had been caring for her 2-year-old granddaughter at the time. They made that call, according to a statement from police, after a "two-year-old child had been dropped off at [their] home by an unknown individual." That toddler was "supposed to be with her grandmother," the statement continues. "The great-grandparents became concerned for the well-being of the child's grandmother and therefore requested a welfare check." Detectives developed information about the victim's teenaged son's possible involvement, and began searching for him. After dropping the 2-year-old off at the great-grandparent's home, "the juvenile suspect took the victim's vehicle and went to a friend's home," the statement says. The statement adds that the juvenile suspect "was taken into custody by Dallas Police officers without incident and provided a full confession to the Homicide detective."
