PRIOR GUNPLAY BY KILLER GOT AN EASY SENTENCE
FELON FIRES ON VEHICLE WITH INFANT OVER TRAFFIC DISPUTE: On December 22, 2010, St. Mary’s Sheriff Tim Cameron reported that St. Mary’s Sheriff’s Department deputies responded to the area of Sassafras Lane and Zack’s Way in Compton, Md, for a reported man with a gun.
Upon their arrival, they made contact with multiple victims who advised they were driving down the road when a citizen stopped them. After being stopped, an argument ensued over a traffic infraction. During the argument, the defendant, Gregory Wayne Arnold, age 38, of Leonardtown, produced an assault rifle and fired shots at the victim’s vehicle. The victims got back into the car and attempted to flee. The defendant continued firing shots at the occupied vehicle while they drove away. The vehicle was occupied by five adults and an infant at the time of the assault. One victim was transported to a local area hospital for non-life-threatening injuries. Officers responded to the defendant’s residence and detained him without incident.
Detectives with BCI responded and assumed the investigation. During the investigation, a loaded assault rifle and ammunition were recovered. A check of the defendant’s criminal record revealed he is a convicted felon and barred from owning the assault weapon. The defendant was arrested and charged with Assault 1st Degree, Reckless Endangerment, and Illegal Possession of a Regulated Firearm. The defendant remains incarcerated at the St. Mary’s County Detention Center. Additional charges are pending a review with the State’s Attorney’s Office.
On February 17, 2011, Gregory Wayne Arnold Sr. entered a guilty plea to illegal possession of a regulated firearm and reckless endangerment in a plea deal with States Attorney Fritz in St. Mary’s County Circuit Court. THE DEAL: Arnold was sentenced to four years and six months in prison, but the deal allowed for all but one year and six months to be suspended, which allowed for the time to be spent in the St. Mary’s County Jail. A felony assault charge was dropped by Fritz as part of the plea deal.
When serving time in the St. Mary’s Jail, Gregory Arnold Sr. assaulted a correctional officer, and the charge was put on the Stet Docket by Fritz on March 16, 2011.
Prior charges of burglary were filed in both Calvert and Charles counties against the now-deceased gunman who shot his parents, killing his father, before taking his own life.
