DES MOINES, Iowa (AP) -

A judge has upheld the paid suspension of a veteran Department of Transportation employee who sent inappropriate emails to colleagues, including one that depicted a woman's genitalia.

The ruling, made public Friday, says the agency acted appropriately when it suspended 52-year-old Ilo Jon Allen, of Hornick, for five days in August and then 10 days for a different situation involving smoking on state property.

Allen, a 33-year veteran of the department, was first suspended in August for sending more than 50 inappropriate emails from his personal email account to work emails of some subordinates. One email showed a series of cropped or staged photographs creating the impression of nudity.

Allen told The Des Moines Register that he didn't realize the emails were against state policy.
