David Carradine

The forensics expert enlisted by David Carradine's family to investigate his death says he did not commit suicide, but that more information is needed from Thai investigators to determine how the Kung Fu and Kill Bill actor died.

"To reach a final determination as to the cause and the manner of death we must wait for further information from Thailand, as to the scene findings and the completion of the crime laboratory and toxicology studies that are still being performed," Dr. Michael Baden said in a statement released to The Associated Press through Carradine's brothers, Keith and Robert Carradine.

In the family's first public statement since Carradine was found hanging in a Bangkok hotel, 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 told the AP.

They also released a statement from Baden saying his autopsy determined Carradine didn't kill himself.

Baden, host of HBO's Autopsy, told the AP he expects to receive more information from Thai authorities in a week or two. "The autopsy is only part of the analysis," he said.

Meanwhile, tributes to Carradine continue. Spike TV announced Thursday that it plans a marathon of his films this weekend, beginning Saturday at 2 pm.
