Eight defendants who allegedly operated a residential burglary ring that targeted Los Angeles Times subscribers named on stolen “vacation hold” lists have pleaded not guilty to more than three dozen charges contained in a grand jury indictment, the Los Angeles County District Attorney’s Office has announced.

Prosecutors said the eight defendants stole an estimated $1 million during dozens of residential burglaries in Los Angeles and San Bernardino counties.

The 39-count indictment named the defendants as Randal Joseph Whitmore, 44; Duane Vantuinen, 52; Joshua Ray Box, 44; Lorraine Marlene Vasquez, 41; Cory Mulligan, 22; Brian Thomas Duran, 42; Margaret Mary Susan High, 29; and Edwin Lynn Valentine, 53. They are charged with multiple counts each of first degree residential burglary, receiving stolen property and conspiracy.

Deputy District Attorney Mark Inaba with the Organized Crime Division, said an extensive investigation was led by the Los Angeles County Sheriff’s Department. The investigation was launched following a June 24, 2012, traffic stop involving Whitmore. Police allegedly discovered stolen property in the car along with L.A. Times “vacation hold” lists that contained the names and addresses of subscribers and the dates that they were scheduled to be out of town. All eight defendants are being held on more than $1.6 million bail each. If convicted as charged, each faces at least 20 years in state prison.
