A third man arrested in the death of an American who was killed while attending a bachelor party in Toronto appeared in court briefly on Tuesday .
Andrew Christopher O'Brien faces a charge of second-degree murder and turned himself in to police on Monday night.
O'Brien is accused along with two others in the beating death of Julian Jones.
The Maryland man died Nov. 5 after what police allege was an unprovoked fight.
Jones was in Toronto to celebrate a friend's upcoming wedding when police allege he and his friends were approached by a group of men outside a bar looking for a fight.
Police say Jones got separated from his friends and was punched and repeatedly kicked in the head even after he lay semi-conscious on the sidewalk. He died while he was being rushed to a hospital.
O'Brien, 28, was accompanied by his lawyer as he gave himself up at a police station Monday night.
After O'Brien's court appearance on Tuesday, his lawyer Christophe Preobrazenski said the case was "tragic all along" but said his client "didn't do it."
"He's not guilty," Preobrazenski said. "It's a case that will have many twists."
He said O'Brien was a "hardworking young man" who works in construction and has a young family.
Two other men, Kenneth Omorojbe and Kamari Folkes, have already been arrested and charged with second-degree murder.
