The Stockton Record reports that its telephone calls were among those secretly monitored by police who were investigating the murder of 8-year-old Sandra Cantu of Tracy.

“All communications … from April 8, 2009, to April 13, 2009, from phones registered in your name, and/or by you, were intercepted and monitored,” Chief Deputy District Attorney Ron Freitas wrote in the undated letter sent to The Record.

The letter disclosing the wiretapping is required by law.

San Joaquin County Superior Court Judge Richard Vlavianos signed an order allowing the wiretaps. Another judge in that county, Linda Lofthus, has imposed a gag order prohibiting officials involved in the case from commenting.
