Also Live at Five Video, again from KATV.
More video here According the police statement (video) she was not stabbed or cut, just blunt force trauma to upper torso and head.
To me that makes it sound more like an intentional beating than a robbery.
They could not find any sign of forced entry. No suspects right now.
Police looking into possibility of "other than robbery" as a motive, because she is a public figure.
Video at link.
As of around 9 PM they are still reporting that she is in critical condition.
