"I don't know if they hit me with something. (They) might have kicked me. Then, blood started coming down my shirt," Martinez said.
His friend, John Ciampoli, does not remember the attack.
"I got 6 stitches on my lip," Ciampoli said.
Ciampoli has trouble talking. He also received stitches on his ear.
"I don't think I said anything or did anything that would have caused anybody to assault me like that," Ciampoli said.
Later that night and two blocks away from where Ciampoli and Martinez were attacked, authorities said a cook was violently robbed. Dustin Lowe was waiting for a ride home. Detectives released new surveillance video, which they said, shows who beat up Lowe, hospitalizing him.
