AUSTIN - (AP) -

A new review by the State Fire Marshal's Office of old arson cases that might have relied on bad science has so far discovered three questionable convictions.
    
But the effort has also drawn criticism from a West Texas prosecutor whose office has had one of its convictions questioned. The prosecutor is now asking the office of Texas Attorney General Greg Abbott to stop the reviews.
    
The Austin American-Statesman reports (http://bit.ly/19VWQ3Q ) four reviews have been completed by a six-member panel of fire, forensic and legal experts that was put together by State Fire Marshal Chris Connealy.
    
Three of the reviews found notable problems with the fire science. One case presented no problems, and a similar finding will be made in a fifth case that will be completed at a December meeting.
