TORONTO -- Toronto police are keeping tight-lipped about what, if anything, they found during a search of a farm owned by a man charged in the death of a Hamilton father who disappeared after taking two men on a test drive.

Const. Tony Vella says homicide investigators finished going through the Waterloo Region property owned by 27-year-old Dellen Millard on Thursday.

He says the search started Tuesday in connection with the 2012 disappearance of Laura Babcock, a Toronto woman who has been linked to Millard, and the death of Millard's father, which was ruled a suicide.

Vella would not say if any evidence was recovered, or if the two investigations have been aided in any way by police scouring the farm site, stating only that the probes are ongoing.

Millard is facing charges of first-degree murder, forcible confinement and theft of a vehicle in the death of Tim Bosma, who did not return after leaving his home May 6 for the test drive of a truck he was trying to sell online.

His remains were found burned beyond recognition at the farm.

Another man, Mark Smich, 25, is also charged with first-degree murder in the Bosma case.
