Connecticut officials are asking the state's highest court to revoke Kennedy cousin Michael Skakel's bail and send him back to prison, reminding justices it has been more than a year since they reinstated his murder conviction.

The chief state's attorney's office filed the request Monday with the state Supreme Court.

Skakel, a nephew of Robert F. Kennedy and his widow, Ethel Kennedy, was convicted of murder in 2002 in the bludgeoning death of Martha Moxley in their wealthy Greenwich neighborhood in 1975, when they were both teenagers.

He was sentenced to 20 years to life in prison. But another judge granted him a new trial in 2013, citing mistakes by his lawyer. Skakel was then freed after being allowed to post $1.2 million bail while he awaited the new trial.

Prosecutors appealed the lower court ruling to the state Supreme Court, which reinstated the conviction in December 2016 in a 4-3 ruling. Skakel's lawyers asked the high court to reconsider the decision — a request that remains pending. Skakel has been allowed to remain free on bail pending that ruling.

In Monday's petition to the Supreme Court, prosecutor James Killen wrote the court's usual practice is to rule on a request to reconsider a decision within weeks, and it's not clear why it is taking so long.
