Mystery -- Who Hit Walking Mike?

Cook County Sheriff's police are looking for the driver who hit a man known as "Walking Mike" whose body was severed because of the force of the collision.

It is a horrific story -- police say Michael Cranston's legs and feet were found in Matteson Friday night. Walking Mike's body was found in Alsip on Sunday.

Cook County Sheriff Tom Dart says police have evidence that will lead them to the driver who hit and ran after crashing into Michael "Walking Mike" Cranston. News reports say parts of the car left at the scene and in the victim's body had serial numbers.

Reports the Chicago Tribune:

"We're going to catch this [driver]," Dart said Monday at a news conference outside Cook County Jail.

"It's just a matter of whether they want to come in at this juncture right now and come off as someone who might be somewhat reasonable and had panicked, or someone who we're going to handcuff and bring in down the road. . . . If we have to go out and get them ourselves, there is little mercy that will be seen for a person like that." ...

"I can't conceive of a scenario where the driver didn't know they hit this individual," Dart said. "This is a situation where a person hit the individual and decided they were going to conceal it." ...

"An individual who wanted to cover up that crime immediately had a forest preserve right there, readily available," Dart said. "Does that mean that the [driver] lives in the general area where the body was found? We're narrowing all that down right now."
