Rebecca Ann Lelar, 32, a nurse who worked with people in Philadelphia who struggled with mental illness and chronic homelessness, died Sunday, July 1, in her Germantown apartment.
Her family believes she died of a heart attack, said Brynn Scriber, 31, a colleague and close friend. Jeff Moran, a spokesman for the city Medical Examiner's Office, said Thursday that the cause of death was pending.
Miss Lelar worked for the nonprofit Pathways to Housing, which provides housing and services for people who have lived on the streets and have had mental-health problems.
