Investigators reconsidering two investigations tied to Tim Bosma murder suspect Dellen Millard

The ongoing investigation into the death of Ontario father Tim Bosma and the man who has been charged with his murder has led investigators down several dark paths in recent days.

The announcement that Dellen Millard has been charged with first-degree murder in Bosma's death has led police to reconsider two other cases – one involving a missing woman who is said to have been last in contact with the young pilot, and the apparent suicide of Millard's own father.

CTV News reports that police are investigating a link between Millard and a 23-year-old woman who went missing last July.

Laura Babcock was last seen in Toronto last summer. Her former boyfriend told the network she was last known to be in the company of Millard and her phone records showed she had called him 13 times between June 30 and July 3, when the phone suddenly stopped being used.

Toronto police told CTV Toronto's Tamara Cherry that nothing had seemed suspicious about Babcock's disappearance until Millard was named as a suspect in Bosma's death last week.

Babcock still hasn't been found. And perhaps as troubling is a report that investigators are also taking a second look into the apparent suicide of Millard's father.

Toronto police have told the Toronto Sun that they are reviewing the death of Wayne Millard. It is currently believed that Wayne Millard committed suicide in his Etobicoke home last year.

The Sun reports that investigators concluded he died of a gunshot wound to the eye last November. It was considered a suicide but the case was never officially closed.

Millard inherited his family's aviation company after the death. His property includes a hangar at the Waterloo Regional Airport and a farmhouse, both of which were searched as part of the Timothy Bosma murder investigation.

Bosma disappeared on the evening of May 6, when he left his family's Ancaster, Ont., home on a test drive with two men who said they wanted to buy his truck.

His body was discovered a week later burned beyond recognition on property belonging to Millard. Investigators are searching for at least two other suspects in the murder – another suspect who took the test drive with Bosma and at least one other person believed to have followed the truck in another vehicle.

Millard's lawyer has said his client will plead not guilty of first-degree murder and that the full story has not come out.

Meantime, the investigation into Bosma's death continues. The Canadian Press reports that police have seized an incinerator found on Millard's property. At last count, police were investigating whether the incinerator had been used in Bosma's death, or possibly after it.

A source told the Toronto Star that Bosma was killed inside his truck on the night he disappeared with two men for a test drive. The source suggested to the Star that it may have been a so-called thrill kill.

“I don’t know the motive for this,” Det. Sgt. Matt Kavanagh told the newspaper. “I don’t even know what thrill kill means. It’s not been discussed.”

While Millard has not been formally connected to either of the re-opened investigations, the incidents paint a troubling landscape on which the Bosma investigation is playing out.

There is more to the story the public has yet to hear.
