Barbara Lydell is a dispatch operator for an armored car company, Security Arms. She was the tipster for robber Charles Roker to assist his crew in jumping the cannabis stores where they were being transported and raiding the stashes. Her husband was in jail and owed Roker, so Barbara was leased for the robberies, while she discussed the plans with her husband signing into prison with her maiden name.
Tracking the armored cars through the company revealed her guilt from the records. She agreed to assist the detectives in catching Roker by citing a fake new mark in a sting. It worked, the police narrowly avoiding the sting being blown by a civilian, and Roker and the gang were arrested.
Barbara's legal status for conspiracy to commit armed robbery and corrupting an official system are unknown. (LA: "Harbor City")
