According to the Goliad County Sheriff's Office, the man was treated at Goliad EMS headquarters for a laceration on his right side. The wound was not life-threatening.
An 18-year-old Victoria man also went to the GCSO at approximately the same time to report he had been punched in the left eye at the party. Medics were called to the GCSO to treat his injury.
According to witnesses, the assailant with the knife was an Hispanic male in his early 20's with a buzz-cut hairstyle and tattoos on his chest and arms. Witnesses told investigators the man who stabbed the victim was described as an African-American who accompanied the Hispanic suspected of the assault on the Victoria man.

There were an estimated 30 to 40 people at the party with the youngest of the participants being 15 years old.
GCSO said the investigation is ongoing.
