Prosecutors say a grand jury will hear evidence against the man arrested in connection with this week's death of a police officer in the northwest Louisiana city of Shreveport.

Twenty-seven-year-old Grover Cannon appeared Friday before Judge Ramona Emanuel through a video link. Emanuel ordered Cannon held without bond in Wednesday's shooting death of Officer Thomas LaValley.

The charge of first-degree murder, which carries a possible death sentence, will be presented to the jury on Oct. 13.

Cannon also has a Sept. 1 court appearance on an attempted second-degree murder charge. Emanuel set $150,000 bond on that charge, which accuses him of shooting Darren Williams on July 15.

During a vigil Thursday night for LaValley, Williams told KSLA-TV ( he was shot while serving court papers on Cannon.
