GREENVILLE, Texas (AP) — A suspected gunman remains on the loose after opening fire at an off-campus college party in Texas, leaving two people dead and 12 others injured.

The search continued today for the unidentified shooter that authorities believe may have been targeting just one person at the party of about 750 people outside Greenville, 15 miles (24 kilometers) southwest of a satellite campus of the Texas A&M University System. They say others may have been shot at random.

The shooting happened about midnight Saturday at what Hunt County Sheriff Randy Meeks described as a Halloween and homecoming party for Texas A&M University-Commerce. Officials said it was not a school-sanctioned event.

Authorities believe there was one male shooter who entered the venue through the back door and began firing with a handgun.
