A surveillance camera on the Roppolo's Pizza trailer near 4th Street and Colorado was rolling during the early morning hours of September 23.
In the video you can see a man wearing glasses and a hat approach the window. Two friends, Andrew Oppleman and Nick Soret, were also there ordering pizza. Eventually, the man in the hat and Soret are seen talking or possibly arguing. Then the suspect tries to take Soret's pizza. When Oppleman gets involved the suspect punches him square in the face and then goes after Soret, knocking him into the counter and hitting him multiple times.
"After this assault the suspect fled on foot, northbound on Colorado Street," said APD Corporal Anthony Hipolito. "He's being described as an Asian male in his late 20's, maybe 30s, 6 foot with a muscular build."
Both men were taken to the hospital. Oppleman lost five teeth and Soret suffered a broken nose and a concussion.
"Both victims sustained serious injuries and that's why we're attempting to locate the main suspect and when he is located we suspect we'll file aggravated assault charges," Hipolito told the news media Friday.
Police believe another man seen in the video, Jin Young Park, seen slumped over the trailer's counter, may know the suspect. Park was arrested that night for public intoxication, but since then, police have not been able to make contact with him.
"Several people around who witnessed assault, we're asking them to please come forward, find justice for these victims," said Hipolito.
The night of the attack Oppleman and Soret had just left Austin's Gay Pride festivities and they believe they were targeted because they're gay. Austin police say the attack was unprovoked, but say it is still too soon in the investigation to call this a hate crime.
Anyone with information about the attack or the suspect should call Austin Police.
