ST. LOUIS – The St. Louis Metropolitan is planning for a change in leadership next month. Current police chief John Hayden is planning to retire, while city officials have selected an interim police chief.

Lt. Colonel Michael Sack has been appointed as interim police chief for the St. Louis Metropolitan Police Department, according to an announcement Wednesday from Dan Isom, director of public safety within the department.

Sack becomes interim police chief in lieu of retiring police chief John Hayden, who will serve his last day on June 18. Chief Hayden announced in September 2021 that he would retire from the police department in February 2022. However, he postponed his retirement in January.

“Beyond staying past his planned retirement date, Chief Hayden has been making sure we have strong hands at the reigns if there was a need to appoint an interim commissioner,” said Isom.

Sack has served with the St. Louis Police Department since 1994. He was promoted to Major in 2015 and served as the commander of the Central Patrol Division. In 2018, he was transferred to the Bureau of Professional Standards as the commander.

“He has shown that he will stand for accountability for the St. Louis Police Department and help foster trust between police and the community,” said Isom. “I know Colonel Sack will continue to give us stability and leadership in this interim phase.”

Sack joined Hayden, Isom and St. Louis Mayor Tishuara Jobnes during an announcement Wednesday afternoon at the Mayor’s Office lobby.

“Everything that I wanted to do at work is focused on creating positive change,” “I’ve learned quite a bit from Chief [Hayden] as well as others throughout my career. … I look forward to working with the mayor and the staff and others commanders on the police department as we go forward.”

The city of St. Louis will continue with the search for a police chief as Sack serves in an interim phase. Isom says the department has also considered candidates from Detroit, Charlotte, and Washington D.C.
