A Miami-Dade Sheriff’s Office (MDSO) lieutenant was arrested early Tuesday morning following a domestic dispute with his wife at their home in Cutler Bay, authorities confirmed.
According to the arrest report, Brian Pfeiffer, 50, and his wife—who share one child—were involved in a verbal altercation overnight. During the dispute, deputies said Pfeiffer grabbed his wife’s wrist, forcibly took her cellphone, and continued arguing before leaving the residence.
Pfeiffer returned home while deputies were investigating and was subsequently detained. He was transported to the MDSO Robbery Bureau for a formal interview, where he denied wrongdoing, providing what the report described as a “self-serving statement.” He was charged with strongarm robbery.
MDSO confirmed Pfeiffer, hired in May 1999, is currently relieved of duty with pay. He was released from the Turner Guilford Knight Correctional Center Tuesday afternoon after posting bond.
The department also noted that Deputy Jordan Aristide was arrested this week on separate domestic violence charges involving his brother.
Sheriff Rosie Cordero-Stutz expressed disappointment over both incidents. “Our deputies are held to the highest standards, and I expect more responsible behavior! Domestic violence has no place in our community, and seeking help is a sign of strength. Help is available, you are not alone!” she said.
