ST. FRANCISVILLE — Trial for the last of the five Angola inmates accused of killing a penitentiary security officer in 1999 has been set for the week of May 20.

The new attorneys for inmate Barry Edge, 52, last month won a delay of the trial that was scheduled to begin Monday with jury selection in St. Tammany Parish.

Edge and four other inmates were indicted in 2004 for first-degree murder in the beating and stabbing death of Louisiana State Penitentiary officer David C. Knapps, 49.

Prosecutors from Jefferson and Caddo parishes, acting for the 20th Judicial District Attorney’s Office, persuaded separate juries to give death sentences for two suspects in the case, Jeffrey Clark and David Brown, while a jury could not agree on a sentence for Robert G. Carley, resulting in a second life sentence for the former New York resident.

A fourth defendant, David Mathis, pleaded guilty to first-degree murder last year and also drew a second life sentence.

Attorneys Steven Lemoine and Nick Trenticosta took over Edge’s defense last year after attorney Nelvil Hollingsworth was arrested with marijuana on his person at Angola and Fred Kroenke lost his certification to handle death penalty cases.

West Feliciana Parish Clerk of Court Felicia Hendl said St. Tammany residents chosen for possible jury duty during a trial set in St. Francisville will fill out a questionnaire on May 17 and return May 20 to begin jury selection.
