Police and prosecutors had alleged that at the time of the fire, Gray was angry with a girl who lived in a two-flat in the 4100 block of South Albany Avenue because she had rejected him. The eighth-grader ignited an accelerant he poured on the enclosed back porch on the second floor and the stairs, according to investigators at the time. While the girl and her parents escaped, the second-floor tenants, Peter McGuiness, 54, and his sister, Margaret Mesa, 74, died.
