FALL RIVER, Mass. -- A judge on Thursday denied bail for former New England Patriots tight end Aaron Hernandez, who is charged with first-degree murder in the shooting death of a friend.

Hernandez's lawyer argued that Hernandez is not a risk to flee and the case against him is circumstantial.

But a prosecutor said the evidence is "overwhelming." A search of a condo leased by Hernandez turned up an ammunition clip matching the caliber of casings found at the scene of the killing of Odin Lloyd, the prosecutor said.

Lloyd's body was discovered by a jogger in a remote area of an industrial park not far from Hernandez's home 10 days ago. He has pleaded not guilty.

Prosecutors called Lloyd's killing an execution-style shooting orchestrated by Hernandez because his friend talked to the wrong people at a nightclub. Hernandez could face life in prison, if convicted.

Hernandez was cut from the NFL team less than two hours after he was arrested and led from his North Attleborough home in handcuffs, and nine days after Lloyd's body was discovered. The 2011 Pro Bowl selection had signed a five-year contract last summer with the Patriots worth $40 million.

Another man, Carlos Ortiz, 27, was arrested Wednesday in Hernandez's hometown of Bristol, Conn., as part of the murder investigation, New Britain State's Attorney Brian Preleski said Thursday. Ortiz was charged as a fugitive from justice and waived extradition to Massachusetts. Prison records show he is being held on $1.5 million bail at a Hartford jail.

Ortiz's public defender, Alfonzo Sirica, declined to comment about the case.

Lloyd, 27, a semipro football player with the Boston Bandits, had known Hernandez for about a year and was dating the sister of Hernandez's fiancee, the mother of Hernandez's 8-month-old baby, Bristol County Assistant District Attorney Bill McCauley said. McCauley said Lloyd was shot multiple times.

At 3:29 a.m., surveillance at Hernandez's house showed him arriving and walking through the house with a gun in his hand, McCauley said.

On Thursday night, Massachusetts state police said they were seeking another man, Ernest Wallace, in connection with Lloyd's killing. They issued an alert and wanted poster for Wallace, saying he was considered armed and dangerous, and sought the public's help in tracking down a silver or gray 2012 Chrysler 300 with Rhode Island license plates he was seen driving.

The New York Times reported that Hernandez is also being investigated as the possible gunman in a double homicide in Boston in 2012, according to a law enforcement official. A second law enforcement official confirmed that Hernandez has been connected to the homicides, which occurred after a fight in a Boston nightclub.

Earlier Thursday, the NFL told its teams that any player contract they enter into with Hernandez before charges against him are resolved won't be approved without a hearing by commissioner Roger Goodell.

The league said the hearing would be to decide if the former Patriots tight end should be suspended or face other action before a resolution of the charges is reached. It said no player contract with Hernandez would take effect before a hearing.
