On Sunday, 7-year-old Jazmine Barnes was killed in Houston. The search for the man who shot up her mother's car for no apparent reason has continued throughout the week as local police continue to pursue leads.

"I'm very confident, and we will not rest until an arrest is made. We are going to continue to search for this killer," said Harris County Sheriff Ed Gonzalez, per CBS News.

Civil rights attorney Lee Merritt and activist Shaun King have raised a $100,000 reward for information leading to finding the killer.

Texans wide receiver DeAndre Hopkins wants to do his part to help the Barnes family. Hopkins posted Thursday that he's pledging this week's playoff check to the Barnes family to help with funeral costs, and he's also hoping to support the efforts of King and the Harris County Sheriff's Office to find the man who killed Barnes.

Hopkins wrote: "When I see Jazmine Barnes' face, I see my own daughter. I am pledging my playoff check this week to help her family with funeral costs and to support @shaunking @SherriffED_HCSO @SylvesterTurner in bringing this man to justice. On Saturday, I will be playing in your honor, Jazmine. #JusticeForJazmine#LoveOverHate"

Hopkins has been one of the best receivers in the NFL this year, hauling in 115 passes for 1,572 yards. He'll look to turn in another big game against the Colts on Saturday, for more reasons than just a football game.
