The West Valley City woman was reported missing Dec. 7, 2009. Authorities had been probing her husband, Josh, who maintained his innocence before killing himself and the couple's two young sons in February at his home in Graham.
Jennifer Graves, Josh Powell's estranged sister, stressed the importance of building healthy relationships through appropriate boundaries during a talk Saturday at the Ivy Girl Academy in Cottonwood Heights.
It ended with a performance of "Susan's Song, 'A Dream Away,'" written by a friend after the boys were killed.
Profits from the song's sale will go toward memorials for Susan Powell in West Valley City and Puyallup, Wash.
