Woman Accused of Killing Football Player's Pregnant Girlfriend to Be Sentenced

The woman accused of fatally shooting the pregnant girlfriend of former Chicago Bears player Shaun Gayle will be sentenced on April 29, 2011. In his first interview, Gayle told "20/20" of how police first thought he was responsible. "They said, 'Do you own a gun?' They wanted to see if I had washed residue from my hands…and they interrogated me for ten hours," he said. Gayle also details how the investigation took a huge turn. Marni Yang, a 43-year-old real estate agent, was accused of killing Rhoni Reuter, who was 7 months pregnant with Gayle's unborn child, on Oct. 4, 2007. According to prosecutors, Yang had been stalking him for years and wanted to eliminate the competition. She faces a possible life sentence. Watch the full story on "20/20" on Friday, April 15, 2011.
