Websleuths was the first on-line site to carry the story of Laurie Murninghan's 1970 murder. Here is a link to another website which has a thread about her.
...The tragic riddle began on July 9th 1970 Laurie Murninghan was
at her summer job as a clerk at Gallagher's Gifts & Antiques at
1010 W. Saginaw St.on Lansings West Side..
Around 2:30pm Thursday,her first day back at work since returning
with her family from a vacation in New Hampshire...
A slim soft-spoken Negro man,around 25 or 30 years old,entered the
shop & asked Laurie to change a $20 bill...
When she said she couldn't change the bill..
The black male pulled a gun siezed her & struck the shop's owner
Mrs. Christine Gallagher with his gun..The gun fired into the ceiling..
Authorities believe the man thought he killed Mrs.Gallagher
So he kidnapped Laurie,the only other witness in the store..
The man grabbed $60 from the cash drawer & fled with
Laurie Murninghan -Kidnapping her at gun-point..
Since she was the only other witness in the store.
At least 4 Witnesses outside in the area of the Gift Shop say:
A black male took Miss Murninghan down an alley at gun point & disappeared...
The search for Miss Murninghan & her kidnapper was one of the
most extensive police manhunts ever held in mid-Michigan history..
But nothing was ever found by law-enforcement linked to the
Murninghan Case..
On July 20 1970 3 young boys looking for pop bottles along a rural
road20 miles southeast of Lansing discovered Laurie Murninghan's body..
16-year-old Laurie Murninghan was found on the edge of the game area
at Barnes and Meridian roads..
Miss Murninghan's badly decomposed body was lying face down
in a swampy area..
In a heavily wooded section of the game area a few feet from the road...
Several weeks later the County Coroner attributed death to Strangulation
& signs she had been Raped..
There is a suspect that matches the witnesses description
of black male gunman..
There was a drug store next to the Gift Shop in 1970..
Black male suspect left prints in the drug store on an inhaler..
The suspect's girlfriend at the time lived 3 blocks from the Crime Scene.
But police did not have enough evidence to convict him..
So her Killer has never been Charged.. ... (More at link)...
