Dallas Police Chief Renee Hall visited the 14-year-old on January 5 to make him chief for a day. She praised officers who came to the family’s aid over the holiday as he fought his illness.

“They go outside of the box of law enforcement, and they touch the human side. This is the community engagement that we only dream about. Because we know that it’s these kinds of things that build a stronger community and help us with our plight on crime and other quality of life issues,” said Chief Hall when she visited the teenager.
