4 now accused of helping alleged Biloxi cop shooter. 2 were out of jail on other charges.

A fourth person has been arrested on an accessory charge of aiding the escape of the teen accused in the shooting death of Biloxi police officer Robert McKeithen.

Gulfport police arrested Andre Sullivan, 18, of Biloxi, late Thursday. He is among three others now in custody on charges of accessory after the fact to capital murder.

Joshua Michael Kovach, 21, and Dalentez Latavian Brice, 20, were picked up late Wednesday night on accessory charges, Harrison County Sheriff Troy Peterson said Thursday morning.

Sullivan, Kovach and Brice are accused of helping 19-year-old shooting suspect Darian Atkinson change clothes to help disguise his identity after the shooting.

They had initial appearances early Friday before Judge Brandon Ladner, who set their bonds at $500,000 each.

However, those bonds were revoked for Sullivan, who already was out on bond on two armed robbery charges, and Brice, who was out of jail on a $50,000 bond for a charge of statutory rape. Brice was arrested on that charge in January.

Atkinson, of Biloxi, is accused of shooting McKeithen, 57, in the parking lot of the Biloxi Lopez Quave Public Safety Center on Sunday night.

Atkinson’s brother, Davian Atkinson, 21, was the first arrested on an accessory charge.

Kovach and Davian Atkinson are the only two eligible to get out of jail on a $500,000 bond.
