NEW: Indpt experts spent 4 days at the Houston home where 2 ppl were killed in a drug raid. They found no signs the pair fired at cops - and plenty of signs that CSI teams did a cursory investigation, leaving behind bullets, tagged evidence & 2 teeth.
“We see no evidence that anybody inside the house was firing toward the door.” New investigation casts doubt on Houston Police Department's account of a botched drug raid that left two people dead in their own home.
One really disappointing thing about this story is that the Houston Forensic Science Center has a stellar reputation. It was set up as an independent lab that was supposed to be free of the bias you often see at crime labs that report to a police agency.
