The black teenager on trial for killing two British tourists in Florida admitted that he was worried he would be tied to the murders after police found bullets in his home

African-American Shawn Tyson was recorded on a phone call from prison to his half brother saying: "They said they found the bullets. That's what I'm saying could f*** me up." He made the call the day after he was held for the murders of James Cooper and James Kouzaris. The black killer is said to have murdered the pair after they drunkenly stumbled into the rundown Newtown neighbourhood of Sarasota. He forced the terrified pair to pull down their trousers before firing a volley of shots. Tyson is accused of going to rob the best friends in April 2011, and then killing them when they said they did not have any money. A court in Sarasota heard that when police searched his home they found two .22 bullets on his bedroom floor. Cooper, 25, and Kouzaris, 24, were shot dead by bullets fired from a .22 revolver.
