Detectives assigned to the Criminal Investigations Division have identified and charged a suspect in a road rage incident. The incident occurred on July 10, 2025, when the victim was stopped at a red light at the intersection of Billingsley Road and Middletown Road. The driver of a motorcycle drove past him and fired several rounds from a firearm, shattering the windows of the victim’s car and causing minor injuries to the victim.  The victim called 9-1-1, and when officers arrived, the victim reported there had been a road rage incident moments earlier between him and the motorcycle driver. Detectives began investigating the case and developed a suspect, Robert Derek Simms, age 36, of Waldorf. Further investigation revealed that Simms is prohibited from possessing a firearm due to a previous conviction. On August 5, a search warrant was served at Simms' residence, and evidence linking him to the shooting was recovered, including a handgun with an obliterated serial number. Simms was arrested at the scene of the search warrant and charged with aggravated assault, weapon violations, and other offenses. On August 14, a judge ordered Simms held without bond at the Charles County Detention Center. Detective Gregory is investigating.
