Mike and Mary Beth Emert of Redmond, Washington, had it all. They were inseparable soul mates. They were also prosperous partners in the competitive world of Seattle-area real estate. Few couples shared a bond so intimate. But on January 4, 2001, their dream life together was shattered. Mary Beth received a call from her mother that Mike had been murdered:

"The realization that he was gone started to sink in while I was still on the telephone with my mom, but still, still hoping that, you know, maybe he was alive and maybe they were wrong, you know. Maybe it wasn't Mike. And I think it was just shock and disbelief."

Mike Emert's murder was as mysterious as it was shocking. It appeared to be carefully planned and meticulously executed. But why would anyone plot to kill an unassuming realtor with an exemplary past? Mike's killer left behind few clues, but enough to make investigators believe he may have used a most unusual weapon.

On the day he was murdered, Mike wrote in his date book that he planned to meet a prospective homebuyer named Steven. He planned to meet him at 11:30 at a local mall. He told Mary Beth that Steven was in his 50s, carried a cane and spoke with an East Coast accent. Steven was interested in a house Mike had shown him the previous day.

At 12:30 PM, the owner of the house, Gail Garland, returned from her job to spend her lunch hour at home. She entered through the garage and was surprised to find the front door ajar. Then she heard the sound of water running upstairs. A trail of blood, still wet, led toward the bathroom. Mike Emert was dead. He had been stabbed 19 times.

Investigators believed that Steven, the supposed homebuyer, committed the brutal murder. They also think Steven chose this house because it was isolated from most other homes in the neighborhood. James H. Doyon was a Detective for the King County Sheriff's Office at the time of Mike's murder:

"It appears that he may have reconnoitered and actually singled out this home as the best place to assault Mike. Now that suggests some sophisticated criminal thinking going on."

If the mysterious Steven had methodically planned Mike's murder, it was also possible that his handicap was merely a ruse. Detective Doyon believed this would explain how a man in need of a cane was able to overpower Mike:

"I think it's possible that the weapon was this cane. And the cane might have been one of these sword canes or a cane with a knife in it. So maybe the initial blitz assault to stun Mike was striking Mike with the cane from behind. The knife portion of the cane was used to kill Mike. Mike was nearly six feet tall, weighed 187 pounds. I think we have an offender here that was able to overcome a man of Mike's stature and then drag his body perhaps about 18 feet from one room to where he came to rest. The water in the shower was turned on, and the two faucets in the vanity sinks were found running. That, to me, speaks of an attempt to get rid of any trace evidence. Hair, fibers, things like that would be washed down the drain. He's cleaning his hands off in the sink, cleaning the weapon off in the sink. This was probably not this individual's first murder, or certainly not his first violent assault."

But if Steven was a professional hit man, who would have a motive to kill Mike Emert? Investigators considered Mike's wife, Mary Beth, and his business rivals as possible suspects. But all were eliminated. They also checked Mike's background to see if he had any enemies who might want him dead. But according to Detective Jon Holland, that probe also proved fruitless:

"While conducting hundreds of interviews with people, even going back 10 years ago, and a prior business that he was involved in, we have not interviewed anybody that can establish why somebody would want to have Mike Emert killed."

Was Mike Emert the victim of a random killing? Or was his death the result of an elaborate murder-for-hire scheme? To this day, this case remains unsolved.
