the gun belongs to her friend who used the vehicle, quote, to visit a football player. investigators say forensic tests prove the gun is the same one used in the boston double murder. the murder weapon in the lloyd case never found. and prosecutors in the lloyd case don't have an eyewitness willing to testify against hernandez. prosecutors in the de abreu/furtado case do. >> we have witnesses, particularly one witness who will apparently say that hernandez did it. >> his name is alexander bradley, the man shot in the eye in florida who refused to tell police who did it. bradley is also the friend with hernandez the night de abreu and furtado are killed. he's talking now, claiming hernandez shot him to shut him up about the double murder. >> he saw, from what we have been told, hernandez open fire at the men in the bmw.
