A Violet man arrested last December in a shootout with several other men was booked Tuesday with illegal possession of a shotgun and handgun by a convicted felon, possession of a large amount of crack cocaine and with being a probation violator, Sheriff James Pohlmann said.

Keith Thompson, 22, of Violet, was arrested by sheriff’s detectives who have been saturating the Violet area as part of the investigation into the shooting death of a man in the same neighborhood on Friday night, Oct. 11, the sheriff said.

Narcotics Division agents and other deputies have also been concentrating in the Violet area as they look into the killing of Joseph “Blue’’ Cosse, 30, shot to death and was found on the lawn of a home.

No arrest has been made in Cosse’s murder but detectives have been following up on leads, Sheriff Pohlmann said.

Thompson was arrested last December after a shootout between two groups, in which no one was injured. He pleaded guilty later to a felony gun charge.

Thompson was booked Tuesday with being a felon in illegal possession of firearms – a shotgun and handgun found in a house in the 3200 block of Daniel Drive – with possession with intent to distribute about 17 grams of crack worth nearly $1,700, possession of a firearms in connection with a controlled, dangerous substance and on the probation violator charge.

He is being held in St. Bernard Parish Prison, unable to be released on bond because of the probation violation.
