FBI Can Look, But Can't Touch Carradine Case

David Carradine's family reached out to the FBI to assist police in Thailand with his death investigation -- but it doesn't look like the agency is gonna be able to make much of an impact.

Thai police Maj. Gen. Amnuay Nimmano told reporters, "If the FBI wants to get involved, we will do our best to cooperate..." and added it would have to be in an observer role as mandated by Thai law, the Huffington Post is reporting.

As of right now most of the evidence points to David's death as an a result of accidental asphyxiation -- especially since there's no evidence someone else was in the room at the time -- but the family isn't buying it.
