Cape Town, South Africa (CNN) -- Mike Steenkamp still wakes up in the morning expecting a phone call from his niece. That call never comes. "It hasn't really sunk in to my way of thinking," he said. Steenkamp and his daughter Kim Martin told CNN this week that they aren't focusing on why Reeva Steenkamp is gone. She was shot and killed just three weeks ago by her boyfriend, Olympian and South African track star Oscar Pistorius. They are trying to avoid the speculation and debate that swirl around whether Pistorius intentionally shot and killed his 29-year-old girlfriend or whether he mistook her for an intruder. He's been charged with premeditated murder.
