Kennedy cousin Michael Skakel will provide a formal alibi for his whereabouts on the night that 15-year-old neighbor Martha Moxley was killed, his lawyer said Wednesday.

Skakel will offer the alibi within 20 days, defense lawyer Michael Sherman said during a motions hearing.

David Grudberg, another defense attorney, told Stamford Superior Judge John F. Kavanewsky Jr. that a murder case against Skakel should be thrown out because there was a five-year statute of limitations in effect at the time of the killing.
