Geron also said police are concerned about the danger of the heat and humidity in Dallas.
According to Dallas News, C.J.'s mother, Dishundra Thomas, has suspicions about the aunt's story.

Anyone with information regarding the abduction or who thinks they may have seen the toddler is encouraged to contact the Dallas Police Department's youth operations division immediately at 214-671-4268.
