Health officials continue to investigate whether the death of an elderly Hagerstown woman is linked to the nationwide E. coli outbreak.

The Maryland State Health Department tells NBC25 that it could be weeks before they know whether 86-year-old June Dunning died from E. coli poisoning after eating raw spinach.

Health officials says a final determination may never be made. The outbreak of the E. coli killed at least one person and sickened 187 others in 26 states.
