MIAMI (AP) - One of two men charged in the 2010 slaying of a Miami mail carrier has pleaded guilty to charges that could send him to prison for life.
    
Saubnet Dwayne Politesse pleaded guilty Monday to charges of conspiracy to affect commerce by robbery, carjacking resulting in death and other counts. Politesse faces a minimum mandatory 10-year sentence and up to life behind bars.
    
Prosecutors say Politesse and fellow defendant Pikerson Mentor robbed and killed 60-year-old mail carrier Bruce Parton at an apartment complex in December 2010. Mentor has pleaded not guilty.
    
Investigators say the pair targeted Parton so they could get a special master key that can open mailboxes in a wide geographic area. Their goal was allegedly to steal people's identities by intercepting mail that contains sensitive personal information.
