The manhunt for the prime suspect in the recent slayings of three Ontario residents has extended into the United States, with his face appearing on the top of the America's Most Wanted website.

Jesse Imeson, 22, is wanted in the murders of William and Helene Regier, a Mount Carmel couple in their 70s, and Carlos Rivera, a 26-year-old bartender at a gay strip club in Windsor.

The Regiers were killed Sunday, while Rivera was found dead last Friday.

Police are hunting Imeson, who was last seen in the Grand Bend area about 75 kilometres north-west of London, Ont.

Details of the crimes and a profile of Imeson have been posted on the America's Most Wanted website, a popular U.S. crime television show.

The profile includes Imeson's picture and photos of a 2006 GMC Sierra truck stolen from the Regiers.

Police are examining a green Ford Taurus they say is connected to the slayings. A provincial police helicopter spotted the vehicle in dense bush near the village of Zurich in Hay Township, about 12 kilometres north of Mount Carmel, on Wednesday night.

No one was inside the vehicle, which was stolen from the area where Sunday's double killing occurred.

A Canada-wide warrant has been issued for Imeson's arrest.

Meanwhile, a bartender says when Imeson walked into an Exeter bar the day before Rivera was murdered, he seemed like "a normal guy."

"He had manners," Melissa Horlor, who works at the bar, told The Globe and Mail.

She said Imeson told a bar patron he was in the United States Army and had fought in Afghanistan. Imeson reportedly had a few drinks with area resident Lindsey Glavin, and the couple left together a while later.

Police have denied reports that Glavin has been given police protection.

Provincial and Windsor police have also refused to comment on Imeson's encounter with Glavin. Neither police force has speculated on where Imeson might be.

On the social networking website Facebook, a London, Ont., woman named Ashley Abbott posted an online conversation she had with Glavin on Tuesday, The Globe reported.

Abbott said Glavin allegedly spent three days with Imeson without knowing he was wanted for murder.

"He's just trying to get up north; that's all I can tell you," Glavin allegedly told Abbott.

During the conversation, Glavin said she was "far enough away that really no one knows where I am."

In an email to The Globe, Abbott said she didn't know Glavin before hearing that she had been seen with Imeson last Thursday night.

"To be honest, I am just like any other concerned citizen from around these parts who are very concerned for their safety," she wrote.

"I had messaged Lindsey on a whim when I saw some messages that were being posted about her saying she was helping (Imeson)."

Glavin told Abbott that Imeson stayed with her for two nights and three days, but she didn't specify which days.

"He ... didn't tell me he was wanted until the third day which is when I got rid of him," she allegedly wrote.

On Wednesday afternoon, Rev. Ray Lawhead read a statement by the Regier family, describing the deceased couple, who were married for 52 years, as "pillars of the community."

Their funerals will be held on Monday in Dashwood.
