NORTH ATTLEBOROUGH, Mass. —Aaron Hernandez "orchestrated" the execution of a semi-professional football player whose body was found near the former New England Patriot star's home, prosecutors said Wednesday as Hernandez was charged with first-degree murder.

Hernandez showed little emotion as prosecutors detailed the evidence against the 23-year-old, which includes surveillance video taken in the hours leading up to the death of Odin Lloyd.

Video shows Hernandez with Lloyd at the former NFL star's home, prosecutors said, and it also shows Hernandez carrying a gun shortly after Lloyd was shot. 

Prosecutors said the victim had been shot in the arms, side and twice in the chest, and ballistics showed he was shot and on the ground when the assailant fired the fatal shots.

Hernandez, who arrived in shackles at Attleboro District Court after being taken into custody at his North Attleborough home, is also facing weapons charges.

Defense attorneys argued that the case against Hernandez is circumstantial and their client is not a flight risk, but the judge ordered Hernandez held without bail. 

Shortly after Hernandez was taken into custody, the New England Patriots released him from the team.

"Words cannot express the disappointment we feel knowing that one of our players was arrested as a result of this investigation. We realize that law enforcement investigations into this matter are ongoing. We support their efforts and respect the process. At this time, we believe this transaction is simply the right thing to do," the team said in a statement.

"The involvement of an NFL player in a case of this nature is deeply troubling. The Patriots have released Aaron Hernandez, who will have his day in court. At the same time, we should not forget the young man who was the victim in this case and take this opportunity to extend our deepest sympathy to Odin Lloyd's family and friends," the NFL said in a statement.
