Carradine's brothers, Keith and Robert Carradine, each read part of a prepared statement to reporters from The Associated Press at a Los Angeles hotel Thursday morning. In their first appearance since their older brother was found hanging in a Bangkok hotel room closet last week, they thanked supporters and asked for privacy.
"This is a devastating loss for our family and we greatly appreciate the compassion pouring in from all over the world," Keith Carradine said.
They also released a statement by Dr. Michael Baden of New York that indicated a second autopsy determined Carradine didn't kill himself.
Reached by phone after the morning briefing, Baden said he expects to receive more information from Thai authorities in a week or two and stressed that the information at hand was incomplete.
"The autopsy is only part of the analysis," he said.
In the meantime, Robert Carradine asked the public and press for patience and time to allow the family to grieve.
"Until we have all of the pending results of the investigation we respectfully ask ... that we be allowed to lay our beloved brother, husband, father, grandfather and great-grandfather to rest in peace and with dignity," Robert Carradine said.
Rampant speculation about the actor's death has swirled since a chambermaid at the luxury Swissotel Nai Lert Park Hotel in Bangkok discovered his body hanging in the closet of his room June 4. A Thai newspaper published a graphic photo of the death scene that police have said appears to be a leaked forensics image.
Thai police initially said they suspected Carradine's death was a suicide, but later conceded it could have been accidental. Their description - that the actor's body was found nude, with ropes around his neck, wrist and genitals - fueled speculation that he was killed while engaging in a dangerous sex practice called auto-erotic asphyxiation.
Others who knew the 72-year-old actor have said they suspect foul play was involved. Keith and Robert Carradine on Thursday urged everyone to wait until the investigation has concluded.
"Once the investigation is fully completed and definitive conclusions have been reached, we will address the findings with the public," Robert Carradine said.
Both Keith and Robert Carradine shared the screen with their brother, a prolific TV and film actor. David Carradine rose to prominence for his role on the "Kung Fu" series in the 1970s and experienced a resurgence in popularity after his role in Quentin Tarantino's "Kill Bill" movies earlier this decade.
The family's statement did not indicate the location of his body, or information about funeral arrangements.
