Members of the Toronto Police Service's homicide squad were acting on a warrant to search the farm of Millard, who has been charged along with a co-accused of first-degree murder after Bosma went missing in early May when he went on a test drive of his truck with two men who answered an online ad.
Toronto homicide unit Staff Insp. Greg McLane had confirmed Tuesday that police were executing the warrant in connection with the disappearance of 23-year-old Laura Babcock and the apparent suicide of Dellen Millard's father, Wayne Millard.
Const. Wendy Drummond confirmed the search was completed.
"Our homicide investigators advise that they will provide any information and full details when they are applicable, but at this time we have no information to disclose," she said.
Investigators were spotted using an excavator to dig pits behind the barn on the property at 2548 Roseville Rd. on Thursday.
Toronto police began searching the property on Tuesday and the work was postponed by wet weather on Wednesday.
Millard, 27, and Mark Smich, 25, of Oakville, Ont., are charged in connection with the death of Bosma, 32, whose burned remains were found on Millard’s farm near Cambridge.
The lawyers representing Millard and Smich have said their clients will plead not guilty. Both men are scheduled to make their next court appearances on June 13 by video.
Police continue to search for at least one more suspect in the Bosma slaying.
