Dellen Millard, accused in the death of Tim Bosma, will be charged with first-degree murder on Wednesday.

Hamilton Police Det. Sgt. Matt Kavanaugh, who is leading the investigation into Bosma’s death, made that announcement at a Tuesday afternoon news conference.

“Investigation has now revealed that Tim Bosma was murdered,” said Kavanaugh.

“He was taken to a location in the Waterloo area where his body was burned beyond recognition. This is now a homicide investigation.

Bosma, 32, was last seen at his Ancaster home May 6 when he left with two men who had asked to test-drive a truck he was selling.

The truck was spotted later that night in Brantford – the same city in which Bosma’s cellphone was found a few days later – and was discovered by police inside a storage trailer near Vaughan.

Millard, believed to be one of the two men who was in the truck with Bosma, was arrested Saturday and charged with forcible confinement and theft under $5,000.

Police say they have interviewed and released several people, but have yet to identify the suspect who accompanied Bosma.

The suspect is described as white with a medium build, 5’9” with dark hair and wearing a red hooded sweatshirt.

“We’re doing everything we can to identify this person and get him under arrest,” said Kavanaugh, who also revealed that a second vehicle, which police have been unable to identify, was present May 6 and was seen following Bosma’s truck.

“When Mr. Bosma’s vehicle left his residence, there was a second vehicle following,” he said.

Police continue to search a farm property on Roseville Road in North Dumfries and a hangar at the Region of Waterloo International Airport, both of which are owned by Millard or his business.

Kavanaugh said Bosma’s remains, which had been burned, were found in one of the two locations.

The investigation at the airport is focused on vehicles in the hangar and has nothing to do with aviation, Kavanaugh said.

Records show that Millard bought the farm property in May 2011 for $835,000 and did not take out a mortgage to do so.

Investigators may be at both locations for some time, as the search warrants are good for two weeks.

Police say search warrants are also being executed on three separate vehicles in Hamilton.

More than 100 officers are working the case on a daily basis.

A tip line has been set up at 905-546-2100, and police say information continues to be left with police every day.
