Kulwinder Kaur Gill Dead: Husband Iqbal Singh Gill, 3 Others Charged

ABBOTSFORD, B.C. - What started as a typical police investigation into the tragic death of a Fraser Valley mother has resulted in first-degree murder charges against the woman's husband and two other men.

The Integrated Homicide Investigation Team has been looking into the death of Kulwinder Gill since she was killed while walking down a rural road in Abbotsford, B.C., with her husband in April 2009.

The woman died at the scene. She was 42 years old and a mother of two children.

Right from the start, investigators thought something was off about the hit-and-run death. The officer in charge of IHIT, Supt. Kevin Hackett, said the team was called in shortly after the woman's death.

"Since 2009, this investigation has been one of IHIT's top priorities," he said in a news release. "We have led a determined and focused investigation and as a result have now obtained the evidence required to bring the investigation where it is today."

The woman's husband Iqbal Singh Gill, 49, has been charged with first-degree murder, along with two other men, Gurpreet Singh Atwal, 26, and 28-year-old Jaspreet Singh Sohi.

A fourth man, Sukhpal Singh Johal, 26, is charged with conspiracy to commit murder and being an accessory after the fact.

The men were all expected to appear in court Monday.

Because the case is now before the court, Hackett didn't want to speak about a motive or discuss evidence connected to the case, but said "it appears that this was well planned and deliberate.

"To the family of Kulwinder Gill, we are sorry for your loss," he said.

"We thank you for your patience and trust."

Hackett said he understood the passing of the years has been difficult for the family and it's been compounded by the fact that police couldn't provide details about the progress of the investigation until very recently.
