A police officer has told a murder trial he seized dozens of letters one of the accused sent to his girlfriend asking her to get their stories straight in case she was called as a witness.
Retired Hamilton police officer Richard Floriani says Dellen Millard sent the letters to Christina Noudga, with the notes laying out a narrative for her to provide if she was asked about Laura Babcock.
Millard and his co-accused, Mark Smich, are charged with killing Babcock and burning her body after she allegedly became the odd one out in a love triangle with Millard and his girlfriend.
Floriani says the notes found at Noudga's home in April 2014 show Millard asked his girlfriend to be his secret agent and warned her that she could be called as a witness.
In the letters, Floriani says Millard told Noudga she needed to put aside whatever she believed about Babcock.
Court heard that Millard then wrote that Babcock had overdosed in his basement doing cocaine.
