Remember Medgar Evers? Civil rights leader shot, buried in the 60's, and then his grave dug up to seek evidence to convict his killer? His body was so perfectly preserved some 30 years after the murder, his wife said he looked as he did the day they buried him.
LE will never know until they do the exhumation. If the BPD actually is investigating this murder again, that's at the top of their list. Another autopsy.
Re-interview Burke, second. No dancing around the facts, either. He's a man now. He should want his sister's killer caught. Give him an LE SPONSORED polygraph test.
Re-interview John Ramsey, third. Ask him the questions that should have been followed up on 12 years ago. Give him an LE SPONSORED polygraph test.
Re-interview John Andrew and Melissa. Give them polygraphs.
Re-interview Lucinda, John's first wife. Give her a polygraph.
Re-interview Patsy's sisters. Give them polygraphs.
Re-interview LHPugh and her daughter.
Re-interview the Whites, the Fernies, the Reverend, the victim advocates there that morning, Linda Arndt, other LE, THE WHOLE SHOOTIN' GANG.
Interview JonBenet's cousins and friends, all now old enough to tell the truth should they know something.
Subpoena all the tapes, films, and audio of any interviews with the Ramseys done by Michael Tracey, CNN, other news programs, and the tapes and notes the ghost writer used to write the "Ramsey's book".
Interview Grandpa Paugh. Give him a polygraph.
Nail down the latest forensic analysis on the ransom note.
"Touch" DNA test the garrote, the duct tape, all the child's clothing she wore, especially the Bloomies, top to bottom, front and back. "Touch" DNA test the blanket and the Barbie gown.
Test the package of Bloomies turned in by the Ramseys, five years TOO LATE, for DNA, fingerprints, including all the the remaining undies inside. Have a forensic lab make a lifesized model of JonBenet's body and use it to study the "too large" Bloomies found on the child.
Subpoena the Ramsey phone records, out of the adjudicated case of the PI's who stole them, as well as if any remain on records anywhere. Determine if that "lost" cell phone had calls from the Ramseys on it AFTER the murder date. Trace phone calls to ANYONE whose number shows up on ANY of the Ramsey records for three months prior, three months after.
Subpoena Dr. Beuf's medical records of JonBenet. Subpoena the medical psychiatrist's records of Patsy Ramsey. Give Dr. Beuf a polygraph test.
Just for starters....
