Three Modesto teenagers charged in the shooting deaths of a married couple and their adult daughter during a robbery at their Modesto market in late January returned to court Monday morning. Defendants Oloth Dicky Phommahaxay, 18, Sophon Theoun Ting, 16, and Chris Douangkham, 15, face three counts of murder in the deaths of Vanh and Phouvieng Thammavongsa and their daughter, Nanci Thammavongsa. The case was continued until April 28 so defense attorneys could have time to review discovery evidence that they had just received from Stanislaus County prosecutors. The hearing lasted only a few minutes. The defendants have pleaded not guilty. Ting and Douangkham are minors but are being charged as adults. Bail has been set at $10 million each for Ting and Douangkham. Phommahaxay is being held without bail at the county jail. Prosecutors have said they believe Phommahaxay broke into the market with the intent of committing a burglary, but it escalated into the robbery and shooting of the Thammavongsas. The criminal complaint says the defendants are members of the CWA Crips street gang, so gang enhancements have been added to their charges.
