LEONARDTOWN, Md. –
It is with profound sadness that St. Mary’s County Government (SMCG) announces the tragic loss of one of our brave officers, Deputy Mark Porter, 60, who died while performing his duties on July 1, 2025.

“Deputy Porter’s longstanding commitment to justice as one of the longest serving deputies in our county was incredible. He will be greatly missed,” said Commissioner President James Randy Guy. May he forever be remembered for his service, and may his legacy inspire us all to appreciate those who risk their lives every day to keep us safe."

Deputy Porter had served in St. Mary’s County for over 34 years, before retiring in 2022. He returned as a contract deputy, following a brief break in service, and continued to serve until his passing. Deputy Porter was one of the longest-serving sworn deputies in the agency, known for his steadfast commitment, integrity, and decades of honorable service to the citizens of St. Mary’s County. He was a trusted colleague and a deeply valued member of our Sheriff’s Office family.

The Commissioners of St. Mary’s County have ordered Maryland State and St. Mary’s County flags to be flown at half-staff in St. Mary’s County, in honor and remembrance of Deputy Porter.

State of Maryland and St. Mary’s County flags will remain lowered in St. Mary’s County until sunset on the day of his interment, honoring his decades of service to the people of St. Mary’s County and the State of Maryland.

For those wishing to express condolences or support, a memorial tribute will be available in the lobby of the Sheriff’s Office Headquarters at 23150 Leonard Hall Drive, Leonardtown, Md.
