Jury to get Angola 5 caseST. FRANCISVILLE — A jury of eight women and four men is expected to begin deliberating Thursday in the first-degree murder trial of Angola inmate David Brown, accused with four other prisoners in the slaying of a security officer nearly 12 years ago.

Prosecutors are seeking the death penalty against Brown in the beating and stabbing death of Capt. David C. Knapps during an escape attempt from Angola’s Camp D Education Building.

Two other officers were taken hostage but later rescued when Angola officials took control of the building.

The prosecutors from Jefferson and Caddo parishes, acting on behalf of the 20th Judicial District Attorney’s Office, presented their last witness Wednesday afternoon, while defense attorneys Mark Marinoff and Clay Calhoun called one witness before resting their case.

Presiding Judge Jerome M. Winsberg told members of the jury, who were chosen in St. Tammany Parish, that they would hear closing arguments from both sides Thursday morning.

If the jurors can unanimously agree on a first-degree murder verdict, a second phase of the trial would begin, probably on Friday, for the jury to decide whether to sentence Brown, 38, to die by lethal injection or to serve a life sentence.

Brown already is serving a life sentence for second-degree murder in the May 1992 shooting death of a Marrero man in Jefferson Parish.

Col. Tim Scanlan, of the Jefferson Parish Sheriff’s Crime Laboratory, testified Wednesday that the presence of Knapps’ blood on Brown’s hands, sweatshirt cuffs, jeans, long john pants and boots is consistent with the defendant’s statement to investigators that he held the victim down while others beat him.

Brown is the third inmate to be tried in the case. Jeffrey Clark was sentenced to death, but Robert G. Carley was sentenced to another life term.

The sweatshirt was found in the restroom where Knapps was killed, and DNA testing showed it had been worn by Brown.

The lone defense witness, Lawrence L. Renner, of Santa Fe, N.M., agreed the blood evidence is consistent with Brown’s statement, but he took issue with the way State Police Crime Laboratory technicians gathered evidence and took photographs of the crime scene.

Renner, accepted as an expert witness, said the building should have been cleared of inmates and security officers to preserve evidence as soon as the threat was ended.
