An infant’s death months ago in a Duluth home is now a case of homicide involving abuse and neglect, authorities have determined.

Five-week-old Jamal T. Chaterlays-Simpson suffered a “severe head injury” on Aug. 8 in a residence in the Gimaajii-Mino-Bimaadizimin apartment building in the 200 block of W. 2nd Street and was hospitalized first in Duluth and then at Children’s of Minneapolis, police said.

The Hennepin County Medical Examiner’s Office said in a statement Wednesday that the baby died on Aug. 10 and “the manner of death is homicide.”

Authorities have announced no arrests.

Duluth police spokeswoman Ingrid Hornibrook said nothing more can be said about the investigation at this time because “the case is recorded as child abuse and neglect.”

An online obituary read that Jamal “lived most of his short life bringing joy and laughter to his family, especially his brother and sister. Jamal left an indelible mark on those who loved him and will be forever missed.”

A memorial service was held for Jamal on Sept. 8 in Cloquet, Minn. Survivors include his parents, Virginia Chaterlays and Sedda Simpson, and siblings James Chaterlays and Victoria Simpson.
