The newspaper article below tells about "DNA-analysis kits" you can get from Applied Biosystems in Foster City, California to help the Police and FBI forces to catch a killer. Consisting of a cocktail of chemicals, Applied Biosystems' kit helps identify DNA from tissue under fingernail clippings taken from the victims.
Regarding the article: In 1985, in Foster City, California, investigators were trying to discover the murderer of Helena Greenwood. Ms. Greenwood, a Del Mar biotech executive and former Atherton resident, was found strangled on her front lawn on August 22, 1985.
They didn't have enough proof to convict David Frediani of the crime at the time, but there soon was enough evidence after using the analysis kit. The kit helped investigators identify the tissue under her fingernails. Even the old fashion police work couldn't have identified her killer. The kit never lies!
This DNA breakthrough technology was originally targeted to help fight diseases and to treat people with medicine.
