Davanh Phouangphet, 32, was convicted in Ottawa County Circuit Court earlier this month of first-degree murder. On Tuesday, Judge Jon Hulsing gave him the mandatory sentence.
Before receiving the sentence, Phouangphet told the judge he set the room on fire, but not his landlady. Police said Phouangphet poured an accelerant on Phanh Kim Le and lit it.
Le died in January 2012 from burns she sustained at the house in Holland Township.
Thong Phouangphet said his brother and Le argued, and the landlady told him to move his music elsewhere in the house or be evicted.
