The Halton police homicide unit has now taken over the investigation into the disappearance of Ozollapa, 50, who has been missing since Sept. 30.
"I just want him to come home," Ozollapa's wife Patricia Harris told CBC News. "The hard part is not knowing what happened."
The couple have a two-year-old daughter Kaysie.
"My daughter, as young as she is, I know she's sensing something is not right," said Harris. "She'll hear a truck and she'll say 'Daddy's truck, daddy's truck.' I don't know what to say to her."
Ozollapa came to Canada from Latvia six years ago and works as a self-employed contractor.
On the day he disappeared he was completing a house renovation job on Weeping Willow Drive, a quiet street in Oakville. At 2 p.m. on that day, he hopped into his pickup truck and left. He hasn't been seen or heard from since.
Surveillance video from a plaza parking lot shows that, on the morning after Ozollapa disappeared, his 2002 Chevrolet Avalanche was dumped at 5:26 a.m. on Cross Avenue, across from the Oakville GO station.
Four minutes later, the video shows an unidentified man running from the truck.
Working on a tip from the public, police found the truck 10 days after Ozollapa disappeared.
Det. Sgt. John Mans of the Halton Regional Police homicide unit said he can't rule out foul play in this case.
Ozollapa is white, six feet tall and 170 pounds with a medium build. He has grey eyes, a goatee, is bald and speaks with a heavy Latvian accent.
He was last seen wearing a T-shirt, blue jeans, brown Crocs and had a black laptop briefcase.
