A man well known in Camden for working with the city's homeless population has been arrested and charged with running a drug market that sold heroin and crack cocaine.

In an indictment dated Sept. 1, federal authorities say 38-year-old Harold "Hal" Miller ran the operation in East Camden.

Miller worked for Volunteers of America before becoming a program coordinator at Joseph's House. In both jobs, he worked with homeless people. Among other services, Joseph's House helps homeless people get drug-addiction treatment.

During his time at Volunteers of America, Miller won the trust of people living in a homeless encampment known as Tent City.

Christopher O'Malley, the federal public defender representing Miller, said he could not comment on the case Tuesday.
