Tim Bosma slaying suspect's farm search halted due to weather

Potentially severe thunderstorms predicted for Southern Ontario Wednesday has temporarily suspended a search by Toronto homicide investigators on a Cambridge-area farm owned by Tim Bosma slaying suspect Dellen Millard.

The property located at 2548 Roseville Rd., near Cambridge, has become the subject of renewed police scrutiny, following the death of Tim Bosma, 32, who disappeared May 6 after taking two men on a test drive in the pickup truck he was trying to sell.

Toronto police homicide investigators had planned a second day of searching for clues in connection with the disappearance of Laura Babcock, 23, and the suicide of the accused killer’s father, Wayne Millard.

However, forecasters are calling for stormy weather Wednesday, with predictions of isolated thunderstorms across much of Southern Ontario, with the potential for torrential downpours, damaging winds and hail lasting until Thursday.

“Due to the weather today, the search of the Millard farm will be postponed and perhaps will continue tomorrow,” Toronto police Const. Victor Kwong said Wednesday.

2nd search since Bosma killing

Homicide unit Staff Insp. Greg McLane confirmed Tuesday that police are following up on recent information that led them to search the farm for a second time since the Bosma slaying.

McLane said police are currently conducting tests at the farm, but would not confirm if they’re digging.

Fresh piles of dirt were spotted at the farm Tuesday and police officers were seen raking and cutting back tall grass with a weed trimmer on the property.

Officers were also observed using a ground-penetrating radar device, which is commonly used to find underground objects.

Millard, 27, was charged with first-degree murder on May 15 in connection with the death of Bosma. A second man, Mark Smich, 25, of Oakville, was arrested on May 22 and has since been charged with first-degree murder. A third suspect is still being sought by Hamilton police.

Babcock has been missing since June 2012. According to friends of the Toronto woman, she was once in a relationship with Millard.

Police have also reopened the investigation into the apparent November 2012 suicide of Millard’s father, whose death was not considered criminal at the time.

After the recent charges against Millard, police said they would take another look at the case.
