U-T San Diego says 37-year-old Patricia Corby received the sentence Monday, about a month after giving a tearful guilty plea to murder.
Several distraught relatives spoke to Corby before the sentencing, including the boy's father Duane Corby who called her "a loathsome person." After several angry family comments she moaned "stop, stop."
On March 31, Corby drove to a police station and told authorities she had killed her son, Daniel, by filling a bathtub and holding the boy under water until he died. His still-wet body was wrapped in a blanket in her back seat.
She says she also tried to drown herself but failed.
