Prince Frederick, MD – A Port Republic man has pled guilty to the murder of a Prince Frederick man back in March of this year, records on file in Calvert County Circuit Court revealed.

Gary Sylvester Mason, 34 entered his plea Sept. 25 in court. Mason was indicted on five counts. The charges stemmed from the death of Rodney Vincent Mackall, 52, who was found severely beaten outside his home March 3. In addition to murder, Mason was facing charges of conspiracy to murder, armed robbery, conspiracy to commit armed robbery, and dangerous weapon, wear and carry with intent to injure.

Mason’s co-defendant, Nicole Danielle Dalrymple, 29 of St. Leonard, was indicted on four counts—murder, conspiracy to commit murder, armed robbery and conspiracy to commit armed robbery. Dalrymple has a criminal motions hearing scheduled for Oct. 8 at 9 a.m. A criminal jury trial on the charges Dalrymple is facing has been tentatively scheduled for Dec. 14.

According to a police report, on March 3 Mason and Dalrymple were driven to Mackall’s residence. It was alleged in the police report that the pair went to the residence to purchase crack cocaine. Mason admitted to police later that he became angry when Mackall said “hello, beautiful” to Dalrymple. Mason told investigators he struck Mackall several times with a mallet and his fist. Dalrymple then allegedly removed crack cocaine and a wallet from Mackall’s pockets.

Police reported that Mackall was found lying unconscious along Sixes Road around 12:40 p.m. that day by an unidentified person who called 911. When Calvert County Sheriff’s Office deputies arrived at the scene they found Mackall laying on the ground bleeding. Mackall was transported to Calvert Memorial Hospital and later transported to University of Maryland Hospital in Baltimore where he died March 4.

Mason was represented at the hearing by attorney Andrew R. Szekely. Mason’s sentencing hearing is tentatively set for Dec. 11 at 10 a.m. in Calvert County Circuit Court.
