This sounds like a Twilight Zone episode.

They thought they had lost their beloved brother for good, taking him off life support and painfully watching him die.

In a shocking bungle, Chicago police misidentified a badly beaten and unconscious patient, leaving a family to mistakenly think he was their relative and remove him from life support, a new lawsuit charges.

The stricken kin only realized the mix-up when the man they thought they had watched die, Alfonso Bennett, strolled up to their home for a family party seven days later, according to court papers.
