Lisa Robin Kelly, 43, best-known for her role in "That 70's Show," died in an Altadena rehab facility Wednesday night.

According to Breaking News Wire, Kelly had checked into the rehab facility Pax House in Altadena earlier this week.

A resident on the 200 block of Wapello Street told Altadenablog that sheriff's cars and the coroner's van were in the neighborhood a good part of the day.  The sheriff watch commander referred all questions to the county coroner.  A coroner's spokesman said that the incident was on "security hold" at request of the sheriff, and no further information would be forthcoming until a public information officer was available Friday.  Cause of death has not been released.
