Every night since May, two-year-old Nylah Cheese has slept with a crocheted doll wearing a white tee, black pants and a silver chain. The toddler’s aunt, Silvia Lopez, had the figurine made in the likeness of Nylah’s father, Brandon Cheese, who was shot and killed at a park in San Francisco the month before.

“She instantly knew it was him and screamed, ‘It’s Dada!’” Lopez, Brandon Cheese’s older sister, said. The toddler has since named it “Dada doll”.

Since Cheese’s killing, Lopez and her family have been working to ensure Nylah knows who her father was and how much he loved her. But for the past 10 months they’ve also been searching for answers about who killed Cheese and why.

San Francisco police have yet to make any arrests.
