Candlelight vigil for Stacy Peterson

Stacy Peterson's family and friends held an evening march and candlelight vigil on the year anniversary of her disappearance.

The group Tuesday night included Peterson's 84-year-old grandfather and people who helped search for the young mother.

The march began at the home where Kathleen Savio, Drew Peterson's third wife, was found dead in a bathtub in 2004. It ended at the Bolingbrook home where Stacy Peterson lived with Drew until her disappearance.

Drew Peterson has been in New York doing television interviews. His home has a "no trespassing" sign on the lawn.

Peterson has repeatedly denied involvement in Stacy's disappearance or Savio's death. He has said he thinks his wife ran off with another man.
