SOUTHWEST JUSTICE CENTER - A jury was impaneled today to try the case of a man accused of fatally shooting another man on the Soboba Indian Reservation six years ago.

Joseph Antonio Resvaloso, 24, is charged with first-degree murder and weapons allegations in the shooting death of Mark Walker on New Year's Day, 2003.

Resvaloso is being held at the county jail on no bail.

Opening statements are set for Tuesday.

Resvaloso allegedly shot at Walker as both met sat in their trucks.

According to Resvaloso's attorney, Karen Lockhart, Walker shot at Resvaloso first, possibly thinking that he was another man with whom the victim had a beef.

The two men -- Resvaloso and the other man with whom Walker had a beef, identified as Gordon Arres -- drove the same kind of truck, Lockhart said.

According to Lockhart's statements during pre-trial motions, Walker approached Resvaloso's vehicle with his own vehicle at a high rate of speed and nearly hit the defendant.

Walker then looked for something on the seat. "The question is going to be, who shot first,'' Lockhart said.

Riverside County Superior Court Judge Albert Wojcik said he would allow the defense to introduce evidence of moral turpitude on the part of prosecution witnesses.

"We want to use it for impeachment,'' Lockhart said, adding that the testimony of some of the witnesses could be suspect because of the close family ties many of the tribal members have with each other.
