An expert from Nike says former New England Patriots tight end Aaron Hernandez was seen on surveillance video wearing the same kind of shoes that left a footprint where an acquaintance of Hernandez was found dead.

Hernandez has pleaded not guilty in the 2013 killing of Odin (OH'-dihn) Lloyd.

Herbert Hedges testified at Hernandez's murder trial Tuesday surveillance video showed Hernandez wearing Nike Air Jordan 11s less than 90 minutes before the killing and less than 10 minutes after. Prosecutors previously said a footprint at the scene was made by that kind of sneaker.

Hernandez's lawyer pointed out more than 3 million shoes with that sole have been made.

Prosecutors also showed videos of headlights heading toward the crime scene and then leaving less than four minutes later. But the video didn't show what kind of car it was.

Former New England Patriots player Aaron Hernandez looked angry when he and a man who was later slain were at a Boston nightclub a couple of days before the killing, an acquaintance of the victim testified Tuesday.

Hernandez's lawyer responded by aggressively questioning Kwami Nicholas, bringing up inconsistencies in what he told police and what he said on the stand.

Hernandez has pleaded not guilty in the June 17, 2013, killing of Odin Lloyd, who was dating the sister of Hernandez's fiancee.

Nicholas testified that he went to Rumor nightclub with several of Lloyd's friends around 11 p.m. on June 14, and stayed until it closed around 2 a.m. His cousin, Jules Nesbit, was a friend of Lloyd's.

Nicholas said Hernandez was also there, and he saw him after the DJ announced the Patriots star was in the club. Previous testimony has established that Hernandez went to the club with Lloyd and another man, whom prosecutors have identified as Hernandez's barber, Roberto Olivares.

In an August 2013 interview with police that was played by the defense team, a police officer asks if he knew what Hernandez looked like before that night.

"I'm a Patriots fan," he replied with a shrug.

Under questioning by prosecutors, Nicholas said he saw Hernandez about 10 to 15 feet away, staring at Odin and another friend. He said Hernandez looked like he was angry, upset and tense.

"Like something was up," he said.

The description was stricken by the judge after the defense objected.

When they left the club, Nicholas testified, he saw Hernandez "storming out of the club" and "walking real fast with his head down."

He said Lloyd ran to chase him but that Hernandez brushed him off.

Defense lawyer Michael Fee went after Nicholas's testimony, repeatedly playing video clips from the 2013 police interview in which his testimony varied, such as about where Hernandez was and what Hernandez was doing or could see at the club.

He also questioned Nicholas' opinion of Hernandez's mood. Nicholas acknowledged he had never met Hernandez before and had never seen him leave a club.

"You're not familiar with Aaron's expressions and what he does with his face?" Fee asked.

"I'm familiar with human expressions," Nicholas replied.

"You have no familiarity with Aaron's face or his expressions, do you?" Fee asked again.

"No, I don't," Nicholas acknowledged.
