PORTLAND, Ore. -- Grammy winning Portland jazz musician and instructor Thara Memory has died at 68, according to Oregon Public Broadcasting.

Memory suffered from diabetes and had been in poor health in recent years.

Memory left behind an impressive legacy of music but more recently had been indicted by a Multnomah County grand jury on eight counts of third-degree sex abuse, two of attempted sexual abuse, and for harassment.

Police said last February that there may be other victims. The status of the case Monday was not immediately available.

Memory won a Grammy with his former student Esperanza Spalding in 2013 for Best Instrumental Arrangement Accompanying Vocalists for the song "City of Roses" from her album "Radio Music Society." The track also features students from his American Music Program.

He founded the music program in 2005 as a way for children to take up jazz instruments and perform.

In May 2015, Memory's students reached an extraordinary achievement. His high school band won the Jazz at Lincoln Center's prestigious Essentially Ellington competition in New York.

Artistic director Wynton Marsalis, who was a judge, said the Portland children impressed him by memorizing one of Duke Ellington's most difficult pieces, "The Tattooed Bride."
