Phanh Kim Le, 53, died Sunday at Spectrum Health Butterworth Hospital in Grand Rapids from burns she sustained Jan. 23 at the house in Holland Township.
Davanh Phouangphet was already in jail and was arraigned Monday on an open murder charge. A judge ordered him held without bond.
A message seeking comment was left last week with the suspect’s court-appointed lawyer.
Thong Phouangphet said his brother and Le argued, and the landlord told him to move his music to another part of the house or be evicted. Police said the suspect poured an accelerant on Le and set her on fire.
