FALL RIVER, Mass. — Two men accused of acting with former New England Patriots player Aaron Hernandez in the slaying of a friend of his behaved strangely days following the man’s death, witnesses testified Friday in Hernandez’s murder trial.

Prosecutors allege Hernandez, Ernest Wallace and Carlos Ortiz picked up Odin Lloyd from his Boston home and drove him to a North Attleborough industrial park, where he was shot to death.

Hernandez has pleaded not guilty to the June 2013 killing. His defense team has been trying to put the blame on co-defendants Wallace and Ortiz, who will be tried separately. Prosecutors have not said who actually shot Lloyd but have said Hernandez orchestrated the killing.

On Friday, David and Elizabeth Gourneault testified that Wallace, a friend of theirs, showed up unannounced at their home in Bristol, Connecticut, within days of the killing and asked to borrow their phone.

“He wasn’t his usual self,” Elizabeth Gourneault said. Wallace stepped outside and used the phone for about 30 minutes before leaving, David Gourneault said.

Members of Hernandez’s extended family through the marriage of his cousin, Tanya Singleton, also testified that Wallace and Singleton – who is accused of helping Wallace flee the state – seemed nervous in the days following Lloyd’s death.

Irene Singleton, the grandmother of Tanya Singleton’s late husband, told the jury that Wallace and Ortiz showed up at her house within a week of Lloyd’s death asking where her grandson was.

“They appeared nervous,” Irene Singleton said of Wallace and Ortiz, adding that the two men huddled together talking in her backyard for about an hour.

Irene Singleton’s daughter, Euna Ritchon, testified that she frequently travels to Georgia to visit her daughter and that within days of Lloyd’s death, Wallace and Tanya Singleton asked if they could drive down with her.
