GEISMAR — An apparent music video production effort Wednesday on a rural lane in Ascension Parish ended in an argument and gunfire, hitting three people and injuring one of them critically. 

Ascension Parish Sheriff Bobby Webre said deputies arrived at Conner Road southeast of La. 73 around 2 p.m. Wednesday to a report of shots fired and found several people fleeing on foot and in vehicles.

He said a group of people are believed to have been filming the video in a trailer near the end of Conner when another group arrived and an argument started.

"We don't know what happened, but the next thing you've got is gunfire and three people hit," Webre said.

He said five to 10 people were in the trailer at the time of the shooting. He couldn't say what the argument was about.

A man was shot in the leg, a woman was shot in the hand and a second man was shot in the cheekbone area. The man shot in the face is in critical condition but is expected to recover, Webre said. The trio were between ages 18 and 22, deputies said.

"The good news is that we think we know everybody involved. … Even some of our victims at the hospital may end up being some of our suspects," Webre said. "So we're trying to piece that together."

By Wednesday evening, deputies and detectives could be seen still working the scene behind police tape and huddling to talk periodically.

Conner is near the end of Stevenson Road, a winding rural lane of older homes and trailers east of La. 73 between Cornerview Road and La. 30. Primarily trailer homes line Conner, a short dead-end road. 

The sheriff said that while the area has had some recent complaints, it is typically a quiet area that doesn't have shootings or other serious crimes. 

Webre said detectives believe the shooting began inside the trailer but also extended outside. 

"Thank goodness nobody's dead," the sheriff said.

Webre said deputies don't believe any guns other than handguns were used in the shooting.

No arrests had been made as of Wednesday evening, Webre said.

Webre said detectives were interviewing witnesses Wednesday but also knew they didn't have everyone who was at the trailer in custody. He couldn't say whether any of the people at large were shooting guns.
