Thomson Police Chief Joseph D. Nelson declined further comment Monday about an apology he issued March 31 for vulgar language.
In a letter released by city hall, Nelson addressed an e-mail he had received in protest of the city's firing of police officer Ruth Hernandez, who is pregnant.
"On Monday, March 28, I responded inappropriately to an e-mail sent to Mayor (Kenneth) Usry and copied to me. I take full responsibility for these inappropriate actions, and I apologize to the mayor and council, and most importantly to the citizens of Thomson," Nelson wrote.
"I also have met with supervision and received appropriate disciplinary action," he wrote. "Again, there is no excuse for professional public servants using language unbecoming as well as responding to provocative e-mails or any other method of communications."
Usry said the letter would be made part of Nelson's personnel file. The chief has 10 days to appeal that action.
Hernandez said she was unable to work road patrol because she is pregnant. She said hers is not a high-risk pregnancy. She said the city did not find a desk job for her and instead fired her.
Nelson, who recently completed one year in charge of the Thomson force, was in the news again this week. He was nominated to attend the National Center for Rural Law Enforcement's Rural Executive Management Institute training course April 11-14 in Denver. Nelson said he plans to attend the event.
Expenses will be paid by the host agency.
Thomson Police Chief Joseph D. Nelson said he has received disciplinary action.
