INDIANAPOLIS (AP): Federal prosecutors are seeking leniency for a former Marion County deputy prosecutor who pleaded guilty to accepting a bribe in exchange for reducing a convicted murderer's sentence.

Prosecutors urged a federal judge in a motion filed Friday to sentence David Wyser to a lesser term than called for under federal guidelines for his crime.

Reports say the motion cites Wyser's cooperation in an investigation of his ex-boss, former Marion County Prosecutor Carl Brizzi. Federal prosecutors announced last month that Brizzi would not face charges that he accepted bribes while in office.

Wyser pleaded guilty in July to federal charges of accepting a $2,500 bribe in 2009 from a prisoner's father to reduce her 70-year sentence on murder charges.
