Heather Mack pleads guilty in US for killing mother in Bali.

Heather Mack, who was convicted in Bali for killing her mother and stuffing her body in a suitcase, changed her plea to guilty in a Chicago federal court to one count of conspiring to kill her mother with her then-boyfriend to get access to a $1.5 million trust fund. Mack hopes to avoid a life sentence. The plea agreement calls for a sentence of no more than 28 years, though the judge hasn't yet decided whether to accept that sentencing cap. The judge set a Dec. 18 sentencing date.
