A 20th person has been charged in an investigation into an alleged Erie to Meadville cocaine ring that authorities broke up in early May, the Pennsylvania Attorney General's Office told Erie News Now Friday.

Police charged Edith V. Henderson, 73, of Meadville, and arraigned her Wednesday on 10 charges.

Henderson used the money from cocaine sales to finance her lifestyle, according to investigators.

She is the mother of Tommy Howard, 46, of Erie, who would travel to Meadville three days per week to sell drugs, according to the Attorney General's Office.

Her arrest comes about two weeks after police charged 19 people as part of a more than a year-long investigation into the cocaine trafficking operation run by Howard.

Henderson was released on unsecured bond after her arraignment. Her preliminary hearing is tentatively scheduled for June 18.
