Two men charged in 1999 Prairieville murder case

Staff reports

Ascension Parish detectives arrested a man and have obtained a warrant for another in connection with the 1999 murder of Thomas Johnson of Prairieville.

Johnson was murdered at his James Road residence in Prairieville Oct. 13, 1999 at about 3:15 a.m., according to Ascension Parish Chief Deputy Tony Bacala.

Detectives found out that Johnson and his family were asleep in the residence when forced entry was made, Bacala reported. Johnson was shot twice and died at the scene, Bacala said.

Detectives obtained a warrant Jan. 15 for Diedrich “Kenny” Rideau, 29, of 15054 Braud Rd., Prairieville, after new information linked him to the homicide, according to Bacala. Authorities suspect Rideau and Nelson Scott went to Johnson’s residence to rob him, Bacala said.

U.S. Marshals and Ascension Parish authorities apprehended Rideau Jan. 20 after he was found in Baton Rouge at a residence on Lake Park Drive, Bacala reported.

Rideau was booked into the Ascension Parish Jail on one count of first-degree murder, said Bacala.

A warrant for first-degree murder was obtained for Scott, 26, of Hollywood St., Baton Rouge, for his suspected involvement in the murder, according to Bacala.

Scott is reportedly being held in the Franklin Parish Detention Center on an unrelated charge, and a hold has been placed on him until he is brought to Ascension Parish to be formally booked at a later date, Bacala said.
