“After week two, it was apparent that the target was heat conscious,” Braile said.

“She was doing U-turns and driving in circles.”

But Braile said Walton — who, along with his wife, Heather, and wealthy businessman Ken Carter are charged with criminally harassing Taylor — continued to track her using GPS devices.

He said he even took part with a then-CPS sergeant, Bradford McNish, in changing devices when the batteries were wearing down.

“My involvement was limited to every 10 to 14 days, swapping the batteries when they were low and covering the child exchange . . . to ensure nothing would go wrong,” he said.

For several months, they would check out the location of Taylor’s vehicle if it left her parking garage.

By February 2013, the surveillance had gone from covert to overt, Braile said.

“He would go to those locations (where Taylor was tracked) and make himself known,” the witness said.

“I was never present, I’m just going by what Steve Walton told me.

“My opinion was he was doing it to intimidate,” Braile said, before Walton’s lawyer, Alain Hepner, objected and Justice Glen Poelman told jurors to ignore the witness’ speculation.

Braile said that at one point he was able to ascertain the unit Taylor was living at in a condominium complex off Bow Trail S.W.

He said he was then directed by Walton to attempt to first obtain a key from the landlord and was later requested to offer to purchase the unit.

“Mr. Walton advised me that they wished to put a listening device or video device within the apartment,” Braile said.

He also had a meeting with Carter after a pen listening device had been purchased online.

“They wanted that pen to be present with (the child Carter shared with Taylor) during a visitation,” he said.

The trial continues on Friday.
