Police never uncovered evidence that the two people accused of killing Jagtar Gill shared details of their alleged crime with one another, an Ottawa courtroom heard Thursday.

Gurpreet Ronald and Bhupinderpal Gill — Jagtar Gill's husband — are both facing first-degree murder charges in the death of the 43-year-old mother of three.

She was found stabbed and bludgeoned to death in the family's Barrhaven home on Jan. 29, 2014.

The two OC Transpo drivers and alleged lovers have both pleaded not guilty.

Conversations tapped in weeks after killing

Police tapped the pair's cell phones and recorded multiple conversations in the weeks after Jagtar Gill's death.

However, Ronald and Bhupinderpal Gill never talked about the killing in those conversations, Ottawa Police Service Det. Chris Benson told court Thursday under cross-examination.

Michael Smith, Ronald's lawyer, asked Benson if police came across any specific instructions the two gave each other regarding the homicide either in phone calls or emails.

"No, there was not," Benson said.

Benson testified that there was no discussion between Gill and Ronald along the lines of "I killed her or I washed the knives or I got rid of the bar" — a reference to a replica of the murder weapon that police planted in Gill's basement and which he later disposed of in a wooded field near his home.

Gill's neighbour, Scott Fewer, has also testified that Gill told him he'd moved his wife's body and — after discovering a pair of bloodied knives — washed them clean in the kitchen sink.

"Killer" note "extreme measure," says lawyer

Earlier in the trial, the jury also heard that police planted a note with the word "killer" on the windshield of Ronald's van, in an attempt to elicit some kind of response.

On Thursday, Smith asked Benson if police uncovered any evidence that Ronald ever spoke with Gill over the note.

"I'm not aware of any," Benson said.

Benson testified that Ronald called security officials at OC Transpo and tried to reach Gill, but her call went unanswered.

Smith called the planting of the note "a pretty extreme measure."

"It could be considered that way," Benson replied. "But to be honest, we didn't have any expectations. We wanted to observe her reaction and see who she might call." 

The trial is expected to continue Friday.
