Prosecutors built their case on the testimony of Medlin and a parade of police officers.

Officers testified that they spent several hours each working day during the 2010 campaign putting up Leopold signs. One said he gathered information on Conti.

Officers also said they drove Leopold on Tuesdays after lunch to the bowling alley parking lot for the meetings with his mistress, and kept watch to make sure that no one happened upon the encounters.

When Leopold was at Anne Arundel Medical Center for back surgery, officers testified, he directed them to ensure that the woman didn't show up at the hospital.

Leopold's attorney's called just three witnesses: Two doctors to testify to Leopold's health in 2010, and the county personnel director, who said she processed Leopold's requests to give some of his pay back to the county.

They also entered his health records into evidence, after asking Sweeney to seal them to preserve his privacy as a patient.
