Police say a Toronto woman who went missing almost a year ago was "romantically linked" to Dellen Millard – one of two men charged in connection with the death of Tim Bosma.

In a news conference on Tuesday, homicide Det. Mike Carbone gave few new details on Laura Babcock. She was last seen in June of last year, and according to phone records, police said she had contact with Millard on July 3, 2012.

"I can say that (Laura and Dellen) were romantically linked although I would not say they had a traditional dating relationship," Carbone said.

He also said Babcock was known to be in the sex-trade business as an Internet escort.

Last week, a farm owned by Millard near Ayr, Ont. was searched by police in connection with Babcock's disappearance, as well as the apparent suicide of Wayne Millard, the suspect's father.

Police confirmed Tuesday that no new evidence was found related to the disappearance of Babcock.

Investigators are now looking for witnesses who were identified in her phone records. They have pulled extensive information from them after getting a production order, giving them access to more details than what a monthly phone bill would show.

According to Babcock's parents and her ex-boyfriend, some of her phone records were handed over to police months ago. But police said they only recently received them after Millard's arrest.

"It’s my understanding that those records were received by 22 Division on the Sunday after the Millard arrest,"Carbone said.

Millard, 27, is one of two men charged with first-degree murder in the death of Bosma, the Ancaster, Ont., man who vanished after going on a test drive in the truck he was trying to sell.

Mark Smich, 25, is also charged.

Babcock was last seen in the Queen Street West and Roncesvalles Avenue area on June 26 of last year.

She is described as white, 135-140 lbs with long brown hair, but has been known to dye her hair blonde. Babcock is deaf in her left ear and has a belly-button piercing.

Police said they still consider this a missing person case.

Carbone said the homicide squad is still reviewing Wayne Millard’s suicide, but Toronto police couldn’t comment any further.

Anyone with information is asked to contact police at 416-808-2280 or Crime Stoppers at 416-222-TIPS (8477).
