A Cook County judge on Tuesday gave William Balfour three life sentences. Balfour was convicted earlier this year of first-degree murder in the 2008 killings. The actress and singer was in the Chicago courtroom for the sentencing.
The sentencing came after Circuit Judge Charles Burns denied a request from Balfour for a new trial.
Balfour faced a mandatory life sentence. Illinois does not have the death penalty.
Balfour was married to Hudson's sister. Prosecutors contend he shot the family members in a jealous rage because she was dating another man.
