UPDATE November 9, 2020- On November 9, 2020, David Harold Johnson entered a guilty plea to three charges involving the killing of Rose Marie Long, age 71, of Prince Frederick, Maryland.  Judge Mark S. Chandlee of the Circuit Court for Calvert County accepted Mr. Johnson’s guilty plea to first-degree premeditated murder, first-degree rape, and motor vehicle theft.  The murder and rape charges each carry a punishment of life imprisonment.  The theft charge carries a maximum of five years imprisonment and/or a $5,000.00 fine.  Sentencing is scheduled for January 11, 2021.

Johnson, age 49, was residing in Calvert County on Sunday, June 7, 2020, when he entered Ms. Long’s home on Stafford Road in Prince Frederick.  Once inside, he raped Ms. Long and strangled her to death using a cell phone charging cord.  He then stole her vehicle and left the area.  

Mr. Johnson was identified as the assailant using Ring doorbell video obtained from Ms. Long’s home.  A lookout was broadcast.  On June 9, 2020, a concerned citizen spotted Mr. Johnson driving Ms. Long’s vehicle on Route 4 in the vicinity of Skinner’s Turn Road.  He called the police, and Johnson was arrested by Sheriff’s Office deputies a short time later.  He ultimately admitted his involvement to detectives from the Maryland State Police.   

Johnson was also identified as the perpetrator through DNA samples obtained from the body of Ms. Long.

The case was prosecuted by Calvert County State’s Attorney Robert H. Harvey, Jr.  Mr. Harvey wishes to thank Cpl. Kyle Simms of the Maryland State Police and his investigative team for their thoroughness, attention to detail, and dedication to the pursuit of justice in this case.   

UPDATE: PRINCE FREDERICK, MD(6/9/2020) — Thanks to an alert citizen who spotted the stolen vehicle, the suspect wanted in connection with the murder of a woman found dead yesterday in her Calvert County home was arrested early this morning by a Maryland state trooper and a Calvert County deputy sheriff.  

The suspect is identified as David H. Johnson, 48, who had been recently living in Prince Frederick, Md.  He is charged on an arrest warrant this morning with first-degree murder, second-degree murder, home invasion, first and second-degree assault, burglary and theft.  Additional charges are pending.  He is being processed at the Maryland State Police Prince Frederick Barrack and will be taken to the county central booking center for an initial appearance before a court commissioner.  

Shortly before 10:30 a.m. yesterday, state troopers from the Prince Frederick Barrack responded to the home of Rose M. Long, 71, of the 200-block of Stafford Road, Prince Frederick, Md., after a relative found suspicious circumstances at the home.  Troopers found the victim deceased in the home.  The home was in disarray and troopers found evidence of an assault.  

State Police investigators from the Homicide Unit and the Criminal Enforcement Division, assisted by crime scene technicians and troopers from the Prince Frederick Barrack, worked through the day and night yesterday processing the scene, collecting evidence and canvassing the neighborhood for anyone who could provide information about a suspect.  

During the night, investigators were able to develop information and evidence that identified the suspect as Johnson.  Investigators obtained an arrest warrant for Johnson and a search was initiated for him.  A lookout for the victim’s vehicle, which was missing from her home, had been issued last night.

Shortly before 5:00 a.m. today, a motorist spotted the victim’s vehicle and called police.  A Prince Frederick Barrack trooper and a Calvert County deputy sheriff located and stopped the car on Rt. 4 at Skinners Turn Road in Owings, Md.  The driver, identified as Johnson, got out of the car and was arrested without incident.  

Investigators believe Johnson had been staying at a home in the victim’s neighborhood during the past few months.  Prior to that, they believe he was living in Washington, D.C.    

A motive for this crime has not been established at this time.  An autopsy is expected to be conducted today on the victim’s body.  

The investigation is continuing.
