Frankie Chavez

Richard sometimes teased his younger sister by calling her Fatso, and Karen shot back by calling him Four Eyes, apparently the sort of sibling needling neither of them regarded as ominous at the time.

Frankie Chavez, who knew Karen well during those years, remembered her as slightly overweight but confident and said he saw no indication that her size seriously troubled her.

Karen herself later remembered things differently.

In a 1973 interview, she described her younger self as much heavier and joked that an old high school sweater looked so large she could hardly believe she had once worn it.
