Search warrant in Oakland County Child Killer case questions polygraph that cleared one-time suspect

BIRMINGHAM, Mich. (WXYZ) - There's new information about a man who was once a key suspect in the Oakland County Child Killer case.

A search warrant just made public shows the lie detector test that was used to clear the suspect decades ago wasn't as accurate as police once thought.

This was the search warrant we tried to get from the court years ago… but detectives kept it hidden until now.

The search was for the home of a man who police once thought was a great suspect. 

Detectives have gone in another direction – and are now looking at other suspects.  But for the father of one of the victims, the details in this affidavit have him wondering if his son could have been spared.

One month before 11-year-old Timothy King was abducted from Birmingham in 1977 – the Michigan State Police were giving Christopher Brian Busch a lie detector test.

King was the last of the 4 known victims of the Oakland County Child Killer.  The first victim was Mark Stebbins.. abducted from Ferndale.

During the polygraph examination, detectives asked  Busch if he'd had anything to do with the Stebbins kidnapping and murder. The trooper administering the polygraph concluded that Busch was being truthful.. and even though he was facing charges in other molestation cases, he was let go.

"You've got a four time charged pedophile who's put back on the street, and if he was involved – he should have been in jail, he shouldn't have been out the night Timmy was abducted," said Timmy King's father, Barry King.

King says the newly released search warrant affidavit shows that thre polygraph experts in 2008 took another look at the Busch test results and determined that he wasn't being truthful.

"It finally confirms what we've been told by people -- that three experienced polygraphers looked at this rookies polygraph results and contradicted his conclusions," said Barry King.

Police reports show that Busch committed suicide in 1978 inside a home in Bloomfield Township.  Using the information about the real Busch polygraph results, and other details – detectives searched the home several years ago.

Officials from the Oakland County Prosecutors Office say none of the hairs or fibers found during  that search connected the murdered children to Busch. In fact, DNA found on both Stebbins and King are actually linked to a totally different suspect in the case.

But Barry King still thinks other details in this search warrant affidavit are critical to the investigation, including this:

Busch told detectives back in '77 that he had picked up children from the same locations in Ferndale, Royal Oak, and Berkley where the kids in the Oakland County case had disappeared from..

"You pick 3 locations in Oak County where he says he picked up children, and the same 3 locations where Stebbins, Robinson, and Mihelich were picked up – I don't think its coincidence," said Barry King.

Barry King is convinced that Christopher Busch played some sort of role in his son's disappearance and murder.

Once again, prosecutors say there is absolutely no DNA evidence tying Christopher Busch to the case. But they continue to aggressively follow all leads in the hopes of solving this tragic mystery.
