The hunt for the suspect in the fatal stabbing of his girlfriend and the shooting of four other people in Alabama ended Tuesday in Louisiana with more bloodshed.

Cortrell Montesez Burks, 50, was taken into custody in Bossier City after authorities say shots were fired during a robbery at a gas station there and a subsequent shootout with police that left two people dead and two others injured, including a police officer.

Burks was not injured in the shootout.

Authorities in Alabama and Louisiana would not confirm that Burks is the suspect in today’s gas station shooting, but the sister of the Alabama homicide victim said she was notified that he was in custody in connection with that incident.

Public records show that a Cortrell Montesez Burks, age 50, was booked into the Bossier City Jail at 6:39 p.m.

Burks has been sought by the Jefferson County Sheriff’s Office and Birmingham police in the Sunday slaying of 40-year-old Erica Shontea Williams.

The Jefferson County District Attorney’s Office on Monday issued a murder warrant against him.

Williams was found stabbed to death about 6:30 p.m. Sunday when Jefferson County sheriff’s deputies were dispatched to her home in the 300 block of 20th Avenue N.E. in the Center Point area on a welfare check.

Williams’ sister, Marva Birchfield, said she received a Facebook message Sunday from an acquaintance saying that Burks had said he had killed Williams.

Birchfield tried to call her sister, and then family went to her home and could get no answer at the door.

That’s when they called 911 and Williams was found dead on the scene.

Birchfield said another sister and three of her nieces were wounded in that shooting. One of the victims remains hospitalized and the other three have been released.

Burks, who is a truck driver, does not have any criminal history in Alabama.

On Tuesday morning, according to Bossier City and Louisiana State Police officials, officers responded to a call of shots fired at a Valero gas station on Industrial Drive at Interstate 20. When Bossier City officers arrived, the suspect emerged from the store and an exchange of gunfire between officers and the suspect took place.

Authorities said the initial shooting happened during at robbery at the Valero.

A Bossier City police officer was struck. He was taken to a hospital in stable condition, with injuries described as “moderate.”

Authorities there held a press conference shortly after the shooting and later issued a press release saying two people are dead and another critically injured. The police officer is stable.

“I’m shocked,’’ Birchfield said. “I can’t believe he did that.”

She said her sister and Burks had been in a relationship for 16 years. She only knows of one prior domestic incident, which happened in January when she said Burks choked Williams. No charges were filed.

Both Williams and Burks have a child apiece, but they did not have any children together.

Williams’ death has devastated her family.

“She was a sweet person. Everybody knew Erica was sweet,’’ Birchfield said. “She’d give you the shirt off her back.
