Hernandez is charged in the June 2013 death of Odin Lloyd, who was dating the sister of Hernandez's fiancee.
Trooper Zachary Johnson testified about going to Lloyd's home the evening his body was found and alerting his family that he was dead. He also spoke about a safe police found in the closet of Hernandez's master bedroom. Inside, he said, was the digital scale and dish.
They also recovered four pairs of white Nike Air Jordan sneakers, he said. Prosecutors have said a footprint by an Air Jordan sneaker was found at the scene.
Trooper Joseph Collins testified about picking up Hernandez's BlackBerry cellphone from Hernandez's lawyer on June 18, 2013, the day after the killing, while Trooper John Conron spoke for more than two hours about how he recovered a digital recorder that held video surveillance from Hernandez's home.
Hernandez's lawyers have tried to poke holes in the state's case by going after how police handled evidence.
