Police in Tracy have launched an internal inquiry into a detective's handling of the Sandra Cantu murder investigation.
In court papers filed last month, the attorney for defendant Melissa Huckaby cited a prosecutor's memo confirming the probe into whether her rights were violated.
At issue are Huckaby's comments to Detective Nate Cogburn on April 10, 2009 — comments that were used to obtain search warrant affidavits. Details were not disclosed in defense attorney Sam Behar's filing in San Joaquin County Superior Court.
If Huckaby's rights are found to have been violated, Behar could ask to toss out key evidence against her. Police declined comment, citing a judge's gag order.
The body of 8-year-old Sandra was found April 6 inside a suitcase dumped in an irrigation pond.
Huckaby has pleaded not guilty to charges of kidnapping, rape and murder.
