LEONARDTOWN — Authorities extradited Delonta Darius Robertson, 21, of Lexington Park, from Florida and booked him into the St. Mary’s County Detention and Rehabilitation Center on November 19, 2025, facing charges of attempted second-degree murder, first-degree assault, and second-degree assault stemming from a September stabbing incident.
Deputies from the St. Mary’s County Sheriff’s Office responded on September 27, 2025, to the 21000 block of Essex Drive in Lexington Park, where they found a male victim with multiple stab wounds to the torso. The suspect had fled the scene prior to their arrival, prompting an immediate search and subsequent issuance of an arrest warrant.
Robertson faces serious felony charges following his location and apprehension out of state. He remains held at the detention center in Leonardtown awaiting a bond hearing.
The incident began with reports of a possible motor vehicle collision involving a pedestrian around 5:17 p.m., but callers quickly clarified a stabbing had occurred during a physical altercation. Emergency responders provided on-scene treatment before transporting the victim for further medical care. The suspected weapon was recovered at the location, aiding the initial evidence collection.
Investigators determined the victim and suspect knew each other, with the attack arising from an ongoing personal dispute that escalated throughout the day into violence. Authorities have stated the event poses no broader threat to the public, as it involved parties acquainted through prior interactions.
Extradition procedures for felony warrants like attempted second-degree murder typically involve coordination between the St. Mary’s County Sheriff’s Office, the State’s Attorney’s Office, and law enforcement in the holding state—in this case, Florida. Once a fugitive warrant confirms the out-of-state arrest, Maryland officials request a governor’s warrant to authorize transport back, a process governed by the Uniform Criminal Extradition Act adopted by most states, including Maryland and Florida. Deputies or contracted transport services then return the individual to face charges locally.
In Maryland, attempted second-degree murder is a felony carrying a maximum penalty of up to 30 years imprisonment upon conviction, reflecting intent to kill without premeditation. First-degree assault, often charged when serious injury results from a deadly weapon, can bring up to 25 years, while second-degree assault covers lesser threats or contacts, with penalties up to 10 years or fines. Prosecutors file these based on evidence of intent, weapon use, and injury severity, with cases proceeding in the St. Mary’s County Circuit Court after district court preliminaries.
