GRAND RAPIDS, MI — It was a brutal 1999 rape of a young woman in downtown Grand Rapids.
The case might have been solved years ago, but for an unusual twist in the circumstances of a suspect – he was an identical twin – and DNA technology could not distinguish between the genetic makeup of Jerome Cooper and his brother, Tyrone Cooper. Both were sex offenders
That was then.
Now, science may have advanced enough to solve the case, police say.
A business called the Center for Advanced Forensic DNA Analysis in Greenville, N.C., claims it can look at genetic mutations to determine which brother committed the crime
