UPDATE July 17, 2018:

The state of Missouri has revoked the peace officer license of a former highway patrol trooper who was driving a patrol boat when a handcuffed Iowa man fell out and drowned, WDAF-TV reports.

Anthony Piercy's license was permanently revoked after the Missouri Department of Public Safety reviewed evidence in the death of 20-year-old Brandon Ellingson, of Clive, Iowa.

Piercy's lawyer, Tim Van Ronzelen, said Tuesday he will appeal the license revocation.

Piercy pleaded guilty in 2017 to negligent operation of a vessel. He was sentenced to two years of supervised probation and 10 days in jail.
