Agent Terry's parents ask to be part of criminal case

Posted: Updated:

TUCSON, Ariz. -- The parents of an Arizona Border Patrol agent killed during a shoot-out want a judge to make them a party in the criminal case against a man who allegedly bought rifles found at the crime scene.

Agent Brian Terry died last December near Rio Rico.

His parents' attorneys made the request so they can stay up to date on the case.

Prosecutors accuse suspect Jaime Avila and nineteen other people of participating in a gun smuggling ring that purchased more than 700 guns for use by a drug cartel.
