Hollis Kirkland McAbee, known as Kirk, was 30 when he was last seen in Durham, North Carolina, on May 23, 2010. He failed to attend his son’s birthday party that day — an absence his mother said he would never have missed. When his estranged wife went to his home on Saddle Drive she found his car parked with the key in the ignition and a large sum of cash on the console.

Investigators learned McAbee had ties to the drug trade and a criminal history. Search warrants and statements from authorities indicate they did not believe he left voluntarily. His wife reportedly admitted to an affair with a friend of Kirk’s who was said to have fled to Mexico after Kirk disappeared. Police also wanted to speak with friend and business associate Armando Reyna-Soto, who investigators believed might have gone to Mexico.

The Durham County Sheriff’s Office says the case has produced no significant leads and remains cold. Does anyone who knew Kirk or his circle in Durham have information that could help resolve what happened to him?
