PRAIRIE VIEW, Texas (KIAH) — The happiness of homecoming weekend for Prairie View A&M University was marred by gunfire Sunday night.

It’s still unclear what led up to the shooting at a party in a pasture off of FM 362 and Cameron Road around 10:30 p.m.

The school released a statement saying that the party was not an official university event.

“PVAMU is both saddened and troubled by the senseless act of violence that occurred in Waller County last night,” the statement read. “Although this was not an official PVAMU homecoming event and was unaffiliated with the University, our campus community is deeply concerned for those injured and all affected by this incident.”

The exact number of victims is unclear as is the extent of their injuries.

The Waller County Sheriff’s Office and other law enforcement agencies used the parking lot at the Buc-ee’s gas station down the road at Highway 290 as a landing zone for medical helicopters.

Witnesses say six people were flown to the hospital for treatment of their wounds.

The sheriff’s office posted on Facebook Sunday that the county judge had approved party promoters’ plans to hold the gathering in the pasture that’s not far from the Prairie View A&M campus.

The post warned people to stay away from the area to avoid the traffic associated with the party.
