On March 3, 2015 at approximately 12:40p.m., the Calvert
Control Center received a 911 call from a citizen reporting a male subject was
lying unconscious along Sixes Road in Prince Frederick. Deputies responded to the area and located a
black male in the shared driveway of 1707 Sixes Road. The male subject appeared to have extensive
head injuries and was bleeding profusely. EMS personnel responded and
transported the subject to Calvert Memorial Hospital.
The subject was identified as Rodney Vincent Mackall of
Sixes Road in Prince Frederick. Mackall
was suffering from severe cerebral bleeding and skull fractures. He was unconscious and unresponsive. Mackall’s injuries were consistent with
injuries caused by a blunt object.
Mackall was said to be in grave condition upon his arrival at Calvert
Memorial Hospital. Mackall was transported to the University of Maryland in
Baltimore for further treatment.
Through investigation It was determined that Nicole
Dalrymple was driven to 1707 Sixes Road by Melvin Johnson. Dalrymple’s husband, Gary Mason, accompanied
her to the Sixes Road address where the assault took place. Allegedly the
purpose of the trip was to purchase crack cocaine.
Mason, Dalrymple, and Johnson were located and taken to the
Calvert County Sheriff’s Office for questioning. Mason advised Criminal Investigation Bureau
personnel that he went to Mackall’s residence with Dalrymple to purchase crack
cocaine. Mason said when they contacted
Mackall he said “Hello Beautiful” to his wife and that made him “Furious”. Mason said he struck Mackall in the head with
a mallet and he fell to the ground.
Mason said he struck Mackall several more times with the mallet and with
his fist. Mason said he and Dalrymple left the area and began to walk towards
Rt. 4 where they were picked up by Johnson. Mason said Dalrymple went through Mackall’s
pockets and took crack cocaine and his wallet.
Dalrymple was also interviewed by detectives and gave
similar statements of the events that occurred on March 3, 2015. Nicole
Danielle Dalrymple, 27, of Port Republic and Gary Sylvester Mason, 35, of Port
Republic, were charged with attempted 1st degree murder, 1st and
2nd degree assault, and armed robbery for their involvement.
Rodney Vincent Mackall, 52, of Prince Frederick succumbed to
his injuries during the afternoon hours on March 4, 2015. Charges on Mason and
Dalrymple will be amended as a result of Mackall’s death.
