Grandzol handed the two brothers his wallet but refused to turn over his car keys because his 2-year-old daughter was still inside, police said.

That"s when he was shot twice in the face, police said. Investigators have not recovered the 9 mm semiautomic gun used to kill Grandzol. They suspect Roberts acquired the weapon by either stealing it or buying it illegally. Sources told NBC10 the two brothers could be heard laughing as they fled the scene.
