CONVENT — St. James Parish sheriff's deputies are still investigating why a man fatally shot his stepfather late Saturday morning in front of a Vacherie convenience store on La. 20, the Sheriff's Office said Monday.

Chief Deputy Col. Sid Berthelot said Monday that Rojae Olando Jackson Dumas has not provided a statement to investigators about the shooting at the Wag-A-Pac store.

"We are still working on establishing a motive," Berthelot said.

Judge Thomas Kliebert Jr., of the 23rd Judicial District, set Dumas' bail Monday at $500,000, Berthelot said.

Deputies found Reynald Jackson, 47, lying face down in the parking lot of the convenience store at 11:09 a.m. Saturday with multiple gunshot wounds, Sheriff Willy Martin Jr. has said. Jackson died at the scene from his wounds.

Deputies later learned that Dumas, 26, 13154 Willow St., Vacherie, shot Jackson, also of Vacherie, Martin has said.

About two and a half hours after the shooting, family members encouraged Dumas to surrender and drove Dumas to a sheriff's substation to turn himself in. He was booked later into St. James parish jail in Convent on a count of second-degree murder, deputies said.
