STAMFORD, Conn. (AP) Kennedy nephew Michael Skakel will be arraigned Feb. 21 for the second time in the 1975 murder of his Greenwich neighbor. But this time, he'll be charged as an adult instead of a juvenile.

Skakel, a nephew of the late U.S. Sen. Robert F. Kennedy and his widow, Ethel, was 15 when Martha Moxley, also 15, was killed on Oct. 30, 1975. The Skakels lived across the street from the Moxleys in the upscale Belle Haven section of Greenwich.

No arrests were made for more than 24 years. Skakel was charged in the killing in January 2000 and later arraigned as a juvenile.

A judge ruled last week that his case should be transferred to adult court, saying Connecticut has no juvenile facility where it could send Skakel, now 40, if he is convicted.

At the arraignment, a charge of murder will be formally read in Stamford Superior Court. From that date, prosecutors have 60 days to schedule a probable cause hearing, where a judge will decide whether there is enough evidence to hold Skakel for trial.

A juvenile court judge already ruled there is enough evidence for a trial, but Skakel must go through the process again in adult court.

The case has been assigned to Judge John F. Kavanewsky Jr., the presiding criminal judge in Stamford, although it is unclear if he will preside at the arraignment.
