The Department of Public Safety and Correctional Services says Krista Blank, of Mount Savage, planned to deliver the contraband to inmates at the medium-security institution.

The agency says alert work by other correctional officers and an internal intelligence unit led to the discovery of the contraband inside a staff restroom at the prison.

Blank could face up to 10 years in prison if convicted on all four counts of marijuana and contraband possession, and possession with intent to deliver the materials inside a prison.

Blank has no home telephone listing and couldn’t be reached for comment.

Sue Esty, assistant director of the Maryland branch of the American Federation of State, County and Municipal Employees, the state workers’ union, said any judgment would be premature until Blank has had an opportunity to present evidence in her defense.
