Deputy Police Commissioner jerry rodriguez. He did suffer a very tragic injury to his spinal cord, which resulted in his death. What we dont know and what we need to get to is how that injury occurred. Reporter rodriguez showed video from Police Security cameras. He also said gray was placed in leg irons during the trip to the hospital and the van made several stops, one to pick up another prisoner, even though gray was pleading for medical help. The handwritten report by the arresting officer says gray was arrested without force or incident, but rodriguez was asked about news reports that an officer subdued gray with a knee on his neck. None of the officers described any use of force. I know that when mr. Gray was placed inside that van, he was able to talk. He was upset. And when mr. Gray was taken out of that van, he could not talk and he could not breathe. Reporter Baltimore Police say the officers initially pursued gray because he ran from them and when they caught him they found he was carrying an illegal switchblade knife.

Lab may have resulted in their convictions. Some of the defendants wont get the notice. Theyve already been executed. Heres Julianna Goldman. I just kept on believing that someone would like into my story. And they would see i was telling the truth, that i was innocent. Reporter Cleveland Wright spent 28 years, nearly half his life, behind bars, convicted in a 1978 murder where prosecutors linked him to hair found near the crime scene. At the time, examiners only relied on microscopic hair analysis, which compares features like shape and color, but in 2012, more accurate d. N. A. Testing on those strands revealed that f. B. I. Lab was wrong. Thank god for the investigators, that theyre looking into other cases, you know. They need to look into other cases. Reporter a new study found that from the 1970s through 1999, most of the f. B. I. s examiners in the hair comparison unit provided erroneous information at trial, and in 268 cases where those forensics led to a conviction, 96 of the time it was based on flawed analysis. Nine of those defendants were executed, while five others died on death row. Those numbers are just from one area. Were going to see a much bigger problem. Reporter dr. Frederic whitehurst is an f. B. I. Whistleblower whose complaints ultimately led to a Justice Department review. It isnt about vindication. Its about the people that have been harmed and our image of our Justice System has been harmed by the f. B. I. s inability to police its own. Reporter there are no indications the mistakes were intentional, and just because there were errors, it doesnt mean that everyone who was convicted was innocent. Scott, today f. B. I. Director james comey said that sometimes justice is when we find a mistake. That means going back to fix it. Pelley Julianna Goldman reporting for us tonight. Julianna, thank you.

Clinging to the wreckage, most of them made it to the safety of europe, but this year alone, for more than 1,000 desperate people from the middle east, asia and africa, their journey to a better life ended in tragedy. The Italian Coast Guard is still scouring the Mediterranean Sea for survivors of yesterdays disaster off the coast of libya, but many here fear theyll only find more bodies. One survivor told italian officials that human smugglers had crammed their 70 foot vessel with more than 900 people before it capsized. Yet many others are ready to take the same risk. We found geele adan sleeping on the street in this small italian city.

It took three days and 18 people died of asphyxiation in the hold, he told us. I prayed to god to save us.
