Two weeks after they were selected, jurors expecting to hear the second-degree murder trial of David Thomas were dismissed Wednesday morning.

The judge dismissed the jury, saying the result of legal arguments over the admissibility of evidence means the trial could be much longer than originally expected.

Thomas, 51, is accused of killing Denise Bourdeau in 2007.

The 39-year-old woman was last seen leaving a New Year’s party in Waterloo, and wasn’t seen again under her remains were discovered months later, near the Grand River.

Police didn’t arrest and charge Thomas in connection with the case until 2011.

A new trial date will be set and new jury selected beginning in February.
