SAGINAW, MI—Emotionally distant father Bill Wolk, 55, immediately handed the phone to his wife Monday upon identifying the caller as his daughter. "Oh, hello, Jessica, I'll get your mom," said Wolk, passing Jessica off before she even asked for anyone. In the past five years, Wolk's most touching display of fatherly affection was a 1996 remark that Jessica "marched nice and straight" with her high-school band in the Rose Bowl parade.
