JUNEAU -- Prosecutors want more time to decide whether to call a key figure in an Alaska corruption case in the retrial of former state lawmaker Vic Kohring.

In court papers filed Tuesday, prosecutors said they're working to finalize travel arrangements to New Mexico, where Bill Allen is serving his sentence. Prosecutors were to have made a decision on whether to call Allen by Wednesday but said they need until Sept. 30.

Allen was chairman of a now-defunct oil field services company who pleaded guilty to bribery and tax violations in a wide-ranging corruption probe that ensnared Alaska politicians, including Kohring.

A Kohring attorney filed papers last week signaling the defense's plan to call Allen.

Kohring's 2007 conviction was overturned due to prosecutorial errors. His retrial is set to begin Oct. 31.
