ALFRED, Maine (AP) — An insurance agent charged with promoting prostitution deleted all the email from his office computer a day after investigators raided his mistress’ Zumba dance studio, office and home, a law enforcement computer expert testified Monday.

Frederick Williams of the Saco Police Department told jurors that he found spreadsheets, tax documents and snapshots from Skype video chats on defendant Mark Strong’s computer and on computer equipment belonging to fitness instructor Alexis Wright, who’s accused of using her Zumba studio as a front for prostitution.
