Feared mobster Frank 'The German' Schweihs dead

Reputed mob killer Frank "The German" Schweihs - who had a fearsome reputation even among the most hard-core mobsters - has died.

Schweihs was recently transferred from the Metropolitan Correction Center to Thorek Hospital and Medical Center, where he died Wednesday evening, according to authorities.

Schweihs had been suffering from cancer and had been unable to stand trial with other top mobsters in the Family Secrets case last year. He was finally scheduled to go on trial in October.

Schweihs died from complications related to his cancer, said Assistant U.S. Attorney T. Markus Funk, a prosecutor in last summer's Family Secrets trial.

Schweihs' standing among mobsters was legendary.

In one conversation secretly recorded by the feds, Schweihs tells a man that he won't be around because he has to go commit a murder - as most people would say they have to take out the trash.

The late mobster Michael Spilotro once warned his teenage daughter that if she ever saw Schweihs around their home, she was to lock the door and call the cops, according to testimony in the Family Secrets trial.
