Federal prosecutors in Chicago are asking for up to 11 years in prison for a man who offered advice to his cousin in the 2014 murder of a woman at an Indonesian resort.

Robert Bibbs did not directly participate in the slaying of Sheila von Wiese-Mack. However, prosecutors say text messages Bibbs sent to Tommy Schaefer and comments made to the FBI after the killing showed he encouraged the crime and expected to be rewarded.

Heather Mack is serving a 10-year sentence for helping her boyfriend, Schaefer, kill her mother at a Bali resort. Schaefer is serving an 18-year sentence.

According to the prosecutor's Monday filing, Bibbs texted his girlfriend around the time of the slaying that they were "gonna be rich."

The 26-year-old Bibbs is scheduled to be sentenced next week by U.S. District Judge Rebecca Pallmeyer.
