Kissimmee’s top police officer resigned after the state’s attorney questioned her credibility in a use-of-force investigation.

Kissimmee Police Chief Betty Holland resigned from her post Monday, days after a letter from the Orange-Osceola State Attorney’s Office named her among 11 members of her department whose credibility is being questioned after a police officer was charged with unlawfully beating a man in time of arrest.

Holland is leaving the department after being appointed to its top post in May 2023. Before that, she had been deputy chief since 2018.

The letter from Chief Assistant State’s Attorney Ryan Williams accused officers and supervisors of the Kissimmee Police Department of making misleading or false statements about the internal investigation into Baseggio. As for Holland, it says: “The statements she made in her interview are inconsistent with other affidavits obtained from witnesses. . . These inconsistencies call into question the accuracy or veracity of her statements in the interview.”
