A prosecutor told a jury Wednesday that Nathaniel Davis III “executed’’ Edward James “Juicy’’ Ricks on Dec. 21, 2009, shooting him seven times on Barber Street and then backing his car over him.

“This is not a case of self-defense. This is a murder case,’’ prosecutor Barry Fontenot said during his opening statement to the jury.

Davis, 23, 1275 Mayfair Hill Drive, is charged with second-degree murder in the slaying of the 23-year-old Ricks.

A second-degree murder conviction carries an automatic sentence of life in prison.

Jurors listened Wednesday to a 911 call in which an unidentified man says he saw a young black male shoot another man, then back his car up and run over him at around 3:20 p.m.

The caller, who told the police dispatcher he did not want to be contacted, said he tried to follow the shooter in his car but lost him. Jurors also were shown a video of the crime scene, with Ricks lying face up in the street, and still photographs of the scene.

Cpl. Glenn Hutto, a Baton Rouge Police Department crime scene investigator, testified that 9 mm shell casings were found near Ricks’ body.

Hutto also testified that several live .40-caliber rounds were located across the street, as well as a piece of an ammunition clip.

“A picture is worth a thousand words,’’ Davis’ attorney, Rodney Messina, told the jury in his opening statement, referring to crime-scene photographs of the live rounds and other evidence he believes is favorable to the defense.

The trial is scheduled to resume Thursday. State District Judge Bonnie Jackson is presiding.
