A one-time murder suspect-turned-Crown witness identified a young man in a downtown prisoner's box Tuesday as the man she followed to a murder scene in July 2012.

"That was the same guy...we followed to Flemington where an innocent man was murdered," the woman testified at the trial for Shakeil Wheatle, accused of murdering Daniel Davis.

It was the early morning hours of July 19, 2012.

During his opening address last week, Crown attorney Scott Clarke told the jury 27-year-old Davis had been hanging out with friends outside Flemington Public School in Lawrence Heights when three males in black hoodies approached.

"One of the males called out for them to chill and then they drew their guns and shot Mr. Davis repeatedly," Clarke said.

Clarke told the jury one of the shooters was Wheatle and another was a young man named Jerome Bent.

The witness testifying Tuesday told the jury about several shootings where she was present with Bent.

In May 2012, she testified, she had driven Bent to a townhouse complex at 4020 Dundas Street West where a man was shot and killed. In September 2012, she said, she had been driving Bent near Jane Street and Wilson Avenue when he allegedly asked her to stop the car, pointed a gun out the window — the same gun, she said, that police later found at her apartment — and fired at a man who survived.

And in July 2012, she said, she was driving Bent again when the pair met up with Bent's friends on a side street in the Toronto's west end.

It was there, the woman said, that Wheatle, known as Deegz or Deego, approached her car to talk to Bent.

"He (Wheatle) had asked Jerome to come with him to check his friend in the Jungle area," she said, referring to slang used to describe the neighbourhood of Lawrence Heights.

"I just didn't like the feeling I was getting from him and I just didn't want Jerome to go with him," she said. "His aura (was) very dark and unsettling."

The woman said she tried to convince Bent not to go, but he convinced her otherwise and the two followed Wheatle in another car to Lawrence Heights.

After parking, Bent, Wheatle and an unknown man got out of the vehicles and disappeared into the darkness, the woman testified.

Moments later, she heard "three or four" loud bangs, she testified.

"I just really wanted to think it was fireworks," she said.

"What did you think it was?" Clarke asked her.

"Gunshots," she replied.

Shortly thereafter, she said, Bent walked quickly to her car and the two went home. While pulling out of the parking lot, she said she spotted Wheatle and the unknown male running to the second car.

The woman's testimony does not entirely align with surveillance video shown to the jury last week, in which three vehicles — not two — are seen arriving in the area and the three alleged shooters are seen running to those vehicles on Flemington Rd. — not in the parking lot — after the shooting.

The woman testified that in 2013, she and Bent were charged in connection with several shootings, including the Davis murder, but that her charges were withdrawn after she agreed to give a statement to police.

Defence lawyer Edward Royle suggested the woman gave the damning statement to get out of her own charges and not necessarily because it was, as she testified, the truth.

Royle questioned whether the woman had knowledge that the shootings were going to happen prior to any of the gunfire.

"You had no idea there was going to be a shooting on any of those occasions?" Royle said during cross examination.

"No," she replied.

"None whatsoever?" Royle said.

"None," she replied.

The Crown's star witness — someone who knew Wheatle and agreed to act as a police agent — is expected Wednesday. The jury has been told they will hear a conversation that was secretly recorded between the agent and Wheatle in which Wheatle allegedly confesses to Davis' murder.
