On Sept. 28, 2000, Kim Camm and her two children were victims of a triple murder in New Albany, Ind. They were found shot to death at home in their garage. Kim and her 5-year-old daughter, Jill, were shot in the head. Her son, Brad, 7, was shot in the chest. The murders were reported by Kim's husband, David Camm, a former Indiana state trooper. "In some ways, it still seems like a nightmare that just didn't happen," says Janice Renn, Kim's mother. Three days later, the community mourned for the Camm family. But just hours after the memorial service, police arrested their prime suspect, David Camm, for murdering his wife and two children. Camm, who claims his innocence, has a very good alibi. Eleven witnesses say they were with him at the time of the murder. It's simple police work to suspect the survivor when family members are murdered. But this case quickly became very complicated. David Camm is from a very large, prominent family in the county, and he has what seems like an airtight alibi. On top of that, there's no obvious motive for these murders. So proving what happened behind these garage doors, beyond a reasonable doubt, is going to be very tough. Correspondent Richard Schlesinger reports in this, the firstours report on these murders.
