Missing or Murdered by R. Barri FlowersFrom award winning criminologist R. Barri Flowers and the bestselling author of Murder of the Banker’s Daughter, Murder at the Pencil Factory, and The Sex Slave Murders, comes an gripping new historical true crime audio short,: Missing or Murdered: The Disappearance of Agnes Tufverson.

On Monday, December 4, 1933, attractive New York attorney Agnes Colonia Tufverson, 43, and Ivan Poderjay, a captain in the Yugoslav army, ten years her junior, got married at the Little Church Around the Corner in New York City. What promised to be a storybook romance for Agnes, with a bright future of travel and adventure turned out to be anything but for the newlywed.

Two weeks after the couple tied the knot and had booked passage on the S.S. Hamburg ocean liner for what was supposed to be a European honeymoon, Agnes Tufverson mysteriously vanished under suspicious circumstances. She was never to be seen nor heard from again.

The chief suspect in her disappearance was new husband, Ivan Poderjay, who not only turned out to be already married, but had other dark secrets and ulterior motives while courting the single and lonely attorney.

But did he kill her? Dump at sea? Or had Tufverson simply decided to drop out of the life she knew and never look back? The authorities in several countries wondered the very same thing.

Read the spellbinding historical and international true story and decide for yourself.

MISSING OR MURDERED is available from Amazon, Audible and iTunes.
