At least two men were killed at an off-campus college party in Texas, local authorities announced on Sunday.

Authorities have not yet found the suspect and were still searching for him Sunday morning, Hunt County Sheriff Randy Meeks said, according to The Associated Press.

Meeks said least four others were hurt at the party near Texas A&M University Commerce, The Dallas Morning News reports. ADVERTISEMENT

Meeks said authorities believe the shooter may have been targeting one person at the party and shot the others at random at the party outside Greenville, Texas near the satellite campus, according to AP.

Meeks reportedly said authorities believe there is one male shooter who entered through the back door of the venue, which he identified as The Party Venue, and began firing with a handgun. Meeks said venue owners are cooperating with authorities, according to AP.

Meeks said the two people killed were men but he did not know if they were A&M Commerce students, according to AP. He also reportedly said that four or five students were believed to be among those injured.

There were about 750 people at the party which Meeks reportedly described as a Halloween and homecoming party. Official said it was not a school-sanctioned event, according to AP.

The sheriff described the party as “complete chaos” as people tried to flee the shooter, and the gunman fled during the commotion, according to the Dallas Morning News.

“It appalls me that, as many folks that were there, [they] have not been able to give us a better description of the shooter,” Meeks said, according to the newspaper.
