Police are worried that a southern Ontario man missing since Monday may have met with foul play after meeting two men answering his online car ad.

Timothy Bosma, 32, of Hamilton, posted his 2007 Dodge Ram pickup truck for sale on Kijiji and Auto Trader.

He left home Monday around 9:20 p.m. with two young men who’d arranged to go for a test-drive and hasn’t been seen since, police said.

Bosma had told his wife the men were from the Toronto area.

Police described the suspects as two white men in their mid 20s. One is about six foot one, weighing 170-180 pounds, unshaven, with short brown hair, wearing jeans, running shoes and a long-sleeve orange shirt. The other is about five foot nine with a small to medium build, wearing a red hoodie with the hood up over his head.

Bosma’s truck is black with Ontario licence plate 726 7ZW.

Anyone who might have information is asked to contact police.
