Shaun Barnett, an Avondale man accused of shooting a Kenner couple in their bedroom last month, will remain in jail without bail while the Jefferson Parish District Attorney’s Office decides whether to formally charge him.

Commissioner Paul Schneider of the 24th Judicial District Court in Gretna found probable cause Wednesday to hold Barnett, who was arrested May 3 in connection with the double killing a month earlier.

Dawn Scott, 28, and Raynell Kimbrough, 31, were found shot to death in their Idaho Avenue apartment the morning of April 4. Their 2-week-old daughter lay alive beside her mother. Scott’s two boys, ages 10 and 2, were also in the home.

Barnett, 28, emerged as a suspect soon after the crime, and Detective Harold Pendergast of the Kenner Police Department testified Thursday that DNA tests on blood found on Barnett’s jacket linked him to the crime, as did witnesses who said they saw him drive away from the scene before Scott and Kimbrough’s bodies were discovered.

Police did not find a weapon when they searched Barnett’s residence, and gunshot residue tests from the scene have not been completed, Pendergast said.

Paul Fleming of the Public Defenders Office argued there is no direct evidence linking his client to the crime and that no witnesses saw Barnett with a weapon.

The judge, however, ordered Barnett held without bail.

On April 4, Scott’s 10-year-old son heard gunshots and walked into his parents’ upstairs bedroom shortly before 7 a.m. to see his mother covered in blood, according to police. The boy ran to the apartment of a neighbor, who called police.

Authorities found Scott lying in the bed next to her daughter. Kimbrough was on the floor next to the bed. Scott had been shot in the head and the torso. Kimbrough was shot in the head and the left flank.

The children were placed in the custody of Scott’s mother.
