A day after a community college president was arrested on drug charges, his wife and two children turned themselves in to police.

Officers seized harvested marijuana worth about $20,000, along with 72 plants, from the home of David England, president of Des Moines Area Community College.

England, 50, was arrested Wednesday on felony charges of growing marijuana to sell. His wife, Donna, 49; their daughter, Jessica, a 22-year-old senior at Iowa State University; and son, a 16-year-old high school junior, turned themselves in Thursday on related charges.

The two-year college, which has about 12,000 students, placed David England on paid administrative leave. The school's board of directors was to meet Friday to discuss the matter.

England's attorney, William Kutmus, declined to comment on the charges Friday. He had told The Des Moines Register that his client would plead innocent.

England was charged with conspiracy to manufacture and deliver marijuana and possession of drug paraphernalia. He was released from county jail Thursday on $50,000 bond.

His wife was charged with conspiracy to manufacture marijuana, and she and their daughter were also each charged with conspiracy to deliver marijuana, as well as possession of marijuana and drug paraphernalia. The son was charged with possession of marijuana and drug paraphernalia, and was released.
