A state panel in Austin has been hearing today from fire experts about the high profile Cameron Todd Willingham arson conviction.  Willingham was convicted and put to death for setting the fire that killed his three daughters in 1991.  He was executed in 2004, But some experts have said the conviction was based on bad science. 

The Texas Forensic Science Commission reviewed the science that was used in the investigation and whether or not investigators were negligent. KUT's Matt Largey is covering panel.
