LOCKPORT, La. — A suspect is in custody in connection with the fatal shooting of a 19-year-old in Lockport Sunday night.

Police identified the suspect as Jyairus Folse, 17, of Lockport.

They did not release what charges may be brought against Folse as of  yet, but said the shooting took place on Sunday, Feb. 10 around 10:30 p.m.

According to officials, Raymond Lambas was sitting on the couch watching TV when someone opened fire on his trailer home just off Highway 308 in the Lockport area.

Lambas says everyone hit the floor and when his 19-year-old grandson, Alton Adamas, got up to investigate, a bullet hit him in the chest.

“When he got shot he hollered at me, he said ‘hold my hand.’ He said, ‘don’t let me die," Lambas said. “His brother put a rag in his back to stop the bleeding, but they couldn’t save him."

Adamas died on the scene.

Lafourche Parish Sheriff’s deputies say it appears the shooter walked through a field behind the trailer and fired into the home. Neighbor Shanon Welch counted about eight gunshots.

“I peaked out our front door, heard the screaming – a gentleman’s voice screaming ‘they shot my son! Call the Cops!” she remembered.

There were seven people in the home when the shooting occurred. Investigators believe the trailer was targeted by the shooter.

“Whether Alton was targeted or someone else in the house was targeted, that’s what we hope to find out,” Lt. Brennan Matherne with the Lafourche Parish Sheriff’s Office said.

Raymond Lambas doesn’t know who would have done something like this and says his grandson was a good boy.

“He kept to himself, he liked to joke around a lot,” he said.
